One of the problems that arise in such a situation is the malfunction of the electronic devices and the loss of information due to the electromagnetic coupling phenomenon induced between the electronic device and the electromagnetic wave generated from the outside. Due to the electromagnetic coupling phenomenon, a portion where interference phenomenon mainly occurs in most electronic systems is a transmission line that is a path through which signals are transmitted.

However, For such a three-dimensional transmission line structure, the accuracy of the analysis may be poor.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating a non-uniform transmission line modeling apparatus for analyzing an electromagnetic wave coupling signal according to an exemplary embodiment of the present invention. Uniform transmission lines.

FIGS. 3A and 3B are structural models of a non-uniform transmission line modeling apparatus for analyzing an electromagnetic wave coupling signal according to an embodiment of the present invention. FIG. FIG. 5 is a diagram illustrating a chain matrix model according to an exemplary embodiment of the present invention. Referring to FIG.

1, an apparatus 100 for modeling a nonuniform transmission line for analyzing electromagnetic wave coupling signals according to an embodiment of the present invention includes a transmission line display unit 110, a coordinate calculation unit 120, and a matrix modeling unit 130).

Prior to describing the configuration of the non-uniform transmission line modeling apparatus 100, the non-uniform transmission line will be described. In this embodiment, the non-uniform transmission line may be embodied on a surface of the ground, consisting of at least two strands of insulated transmission lines twisted in a helical form, as shown in FIG. For example, two stranded insulated twisted wire pairs (TWP) can be formed on the surface of the earth in connection with any equipment (Zinput, Zoutput) at both ends.

At this time, the nonuniform transmission line can be induced along each line by coupling signals due to coupling phenomena with external electromagnetic waves. Here, the induced combined signal may cause an unintended transient response to the arbitrary equipment connected to the non-uniform transmission line.

Accordingly, in one embodiment of the present invention, the non-uniform transmission line is modeled to analyze the degree of transient response of any equipment connected to the transmission line affected by the induced coupling signal.

To this end, the transmission line display unit 110 expresses the non-uniform transmission line as a vertical component, a diagonal component, and a horizontal component on a two-dimensional plane with respect to a longitudinal axis for each unit length of a predetermined length. At this time, the transmission line display unit 110 may divide the non-uniform transmission line into a plurality of unit length transmission lines having a predetermined length, and express each unit length transmission line on the two-dimensional plane with the respective components.

In this embodiment, the longitudinal axis of the non-uniform transmission line is assumed to be the x-axis, and the remaining two axes are assumed to be the y-axis and the z-axis, respectively.

The non-uniform transmission line of FIG. 2 is shown in cross section on the xz plane as shown in FIG. That is, the non-uniform transmission line may be divided into a plurality of unit length transmission lines as described above, and each of the unit length transmission lines may be divided into a first half unit length transmission line (half-TWP # 1) Length transmission line (half-TWP # 2).

Thus, each of the first and second half-length transmission lines half-TWP # 1 and # 2 may be represented by a vertical component, a diagonal component, and a horizontal component, And may have the same length in each unit length transmission line. The vertical component has a length corresponding to half of the lengths of the horizontal component and the diagonal component and is arranged at the first and second ends of the first and second half-unit length transmission lines half-TWP # 1 and # 2. . That is, when the lengths of the vertical components arranged at the first and second half-length transmission lines (half-TWP # 1 and # 2) are added, all components have the same length.

For example, each of the horizontal component and the diagonal component has a length corresponding to 2 DELTA x, and the vertical component has a length corresponding to DELTA x at the start and end portions of the first and second half-length transmission lines, The components can be expressed as a total of 2 DELTA x.

Therefore, if the first and second half-length transmission lines half-TWP # 1 and # 2 shown on the xz plane as the vertical component, the diagonal component and the horizontal component are shown on the yz plane, respectively, Can be expressed as.

In other words, the transmission line display unit 110 may express each half-length transmission line shown in FIG. 3A as components (vertical, diagonal, horizontal) arranged in a circle along a circle as shown in FIG. 3B.

The transmission line display unit 110 may assume that the first and second half-unit-length transmission lines start at positions opposite to each other when the respective components are sequentially arranged on the yz plane.

Specifically, the transmission line display unit 110 arranges the unit length transmission line wire # 1 of FIG. 3A at a position of 1 and the unit length transmission line wire # 2 of FIG. 3A at a position of 2 from the unit length transmission line of two- , So that the twist of the unit length transmission lines (wire # 1, wire # 2) proceeds from the positions of 1 and 2.

That is, the unit length transmission lines wire # 1 and wire # 2 in FIG. 3A can be seen to rotate in the clockwise direction starting from positions 1 and 2 in the opposite direction of 180 degrees, respectively.

Accordingly, the transmission line display unit 110 arranges each of the first and second half-unit length transmission lines in a circle in the order of vertical component-> diagonal component-> horizontal component-> diagonal component, It can be expressed as an array.

The coordinate calculation unit 120 calculates the positional coordinates of each component of the unit length transmission line with respect to each unit length transmission line of the predetermined length.

That is, as shown in FIG. 4, the coordinate calculating unit 120 calculates the distance (d) between the unit length transmission lines for each component and the height (h) from the ground surface to the center of the unit length transmission line, And calculates positional coordinates for each component of the transmission line.

In other words, for each of the unit length transmission lines, the coordinate calculation unit 120 calculates the distance d between the same components among the vertical component, the diagonal component, and the horizontal component, and the height h from the ground surface to the center of the unit length transmission line, The position coordinates of each component of the unit length transmission line may be calculated for each of the same components.

At this time, the coordinate calculation unit 120 calculates coordinate values corresponding to the respective components on the axis x in the longitudinal direction to the same value, assuming that the lengths of the components of the unit length transmission line are the same, Coordinate values corresponding to the respective components on the two axes (y, z) on the two-dimensional plane can be calculated based on the distance (d) and the height (h).

Thus, the coordinate calculation unit 120 can calculate each component as three-dimensional position coordinates on the three axes (x, y, z).

The matrix modeling unit 130 forms a matrix relating to the unit length transmission line based on the calculated position coordinates. That is, the matrix modeling unit 130 may generate the matrix related to the unit length transmission line according to the positional coordinates of each component of the unit length transmission line.

Here, the matrix related to the unit length transmission line may be expressed as Matrix 1 below.

As shown in FIG. 5, the matrix modeling unit 130 creates a chain matrix by connecting the matrices constructed as described above, and distributes a power source to the matrix corresponding to the unit- To generate a chain matrix model for analyzing electromagnetic wave coupling signals of the non-uniform transmission line.

Accordingly, the matrix modeling unit 130 can model the non-uniform transmission line through the multi-connected chain matrix.

At this time, the matrix modeling unit 130 may apply the distributed source to a chain matrix at a position corresponding to the unit length transmission line, based on the Taylor source model.

That is, the matrix modeling unit 130 may convert a current and a voltage converging to an approximation of the coupling signal into the unit length transmission line (s) through the dispersion source, so that an environment in which coupling signals due to external electromagnetic waves are generated in the unit length transmission line is created. So that a chain matrix model for analyzing the electromagnetic wave coupling signal of the non-uniform transmission line can be generated.

Thus, according to an embodiment of the present invention, by modeling non-uniform transmission lines as chain matrices, which are multiple connections of unit length transmission lines, it is possible to analyze electromagnetic interference signals of nonuniform transmission lines exposed to very inefficient environments Environment can be provided.

Here, the method of modeling the nonuniform transmission line may be performed by the modeling apparatus 100 of the nonuniform transmission line of FIG.

6, in step 610, the non-uniform transmission line modeling device generates a non-uniform transmission line based on a vertical axis, a diagonal component, and a horizontal component on a two- Expressed as a component.

Next, in step 620, the modeling apparatus of the non-uniform transmission line calculates a distance d between unit length transmission lines for each component and a height (h), position coordinates for each component of the unit length transmission line are calculated.

Next, in step 630, the non-uniform transmission line modeling device constructs a matrix relating to the unit length transmission line based on the calculated position coordinates, and for the chain matrix obtained by multiplying the constructed matrixes, And generates a chain matrix model for analyzing an electromagnetic wave coupling signal of the non-uniform transmission line by applying a dispersion source that distributes power to a position corresponding to the length transmission line.

As described above, according to the embodiment of the present invention, the electromagnetic wave coupling signal of the non-uniform transmission line exposed to the external electromagnetic wave is measured by using the chain matrix model, and more precise analysis of the electromagnetic wave coupling signal is possible.
