Compact closed-loop resonator based on artificial surface phasmon
Technical field
The present invention is a kind of toroidal cavity resonator, particularly a kind of compact close loop resonance based on artificial surface phasmon Device.
Background technology
Surface phasmon is the surface electricity propagated along metal and dielectric surface being formed under the conditions of certain excitation Magnetic wave, energy of electromagnetic field can be limited in the range of depth sub-wavelength, thus not limited by diffraction limit, in integrated electricity The aspects such as road, communication technology and sensor have huge application prospect.
But the surface phasmon of nature exists only in optical band, in order to compared with low-frequency range (Terahertz, microwave, in the least Metric wave) realize surface phasmon, there has been proposed artificial surface etc. is from polariton.Document 1X.P.Shen and T.J.Cui,“Ultrathin plasmonic metamaterial for spoof localized surface Plasmons ", Laser Photonics Rev.8,137 (2014), disclose a kind of toroidal cavity resonator, as shown in figure 4, this is humorous The device that shakes encloses circular, the equidistant periodic arrangement of grating by the grating (3) of one or more, and the inner circle enclosing (4) is real Heart round metal.Document 2Y.J.Zhou, Q.Z.Xiao, B.J.Yang, Sci.Rep., " Spoof localized surface plasmons on ultrathin textured MIM ring resonator with enhanced resonances”, 5,14819 (2015), disclose a kind of toroidal cavity resonator, as shown in figure 5, this resonator is enclosed by the grating (3) of one or more Circular, the equidistant periodic arrangement of grating, the inner circle enclosing (5) is embedded metal ring in open circles, and grating (6).The resonator of both structures be in the structure between or middle part introduce annulus or disc structure, such surface current Path is too small, and electric size is larger.
Arrowband or the higher resonance ring structure of quality factor have in microwave and millimeter wave device and antenna, communication system It is widely applied.Existing artificial surface phasmon resonance structure is usually the annular inner portion formation equivalent electric in structure at present Stream ring, therefore often electric size is larger, quality factor are relatively low, resonant intensity is weaker.
Content of the invention
It is an object of the invention to provide one kind has higher figure of merit, electric size less compact resonator, should Resonator can be operated in microwave, millimeter wave and Terahertz frequency range.The present invention can be used for resonator and high sensor etc. Design.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of compact closed-loop resonator based on artificial surface phasmon, including an annulus (1) and hollow gold Belong to grating (2), described metal grating (2) includes the grating (21) of one or more, one end of described grating (21) and annulus (1) Inner circle connects, and the other end points to the center of circle direction of annulus (1), and the grating one end in sensing annulus (1) center of circle surrounds metal grating (2) hollow circular gap (22).
Further, described metal grating includes the grating of one or more, and described metal grating is along the inner circle circumference of annulus Periodic arrangement.
Further, by changing the structural parameters of annulus and metal grating, can adjust each mode of resonance frequency, Intensity and Q-value, described structural parameters include the distance between the interior outer radius of described annulus, described metal grating, length and width Degree.
Further, described resonator is hanging metal structure;Or described resonator is printing or is etched in substrate On foil structures.
Beneficial effects of the present invention are:
1st, the electric size very little of the present invention.Existing surface phasmon resonator, usually in the structure between or in Portion introduces annulus or disc structure, and the path of such surface current is far smaller than the structure outermost that the present invention adopts. The size of the present invention can reach about a quarter of operation wavelength.
2nd, the resonant intensity of the present invention is big.Under identical physical size, the change of surface current path can make basic mode The resonant intensity of (dipole) strengthens more than 3dBsm, thus has higher resonance efficiency.This also makes the present invention be applied to There is when transmission-type device and antenna higher efficiency.
3rd, the present invention has high sensitivity and high resonance quality factor.The dipole of the present invention, level Four and six types of severe debility disease Q-value be respectively 17.81,146.5 and 634, far above same type existing structure, thus for design high sensor provide Feasible program.
4th, present configuration is simple and is scaled by equal proportion it is easy to processing, can be operated in Terahertz and microwave, in the least Meter wave frequency band.

Specific embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not limit Qualitatively it is impossible to protection scope of the present invention is limited with this.
As shown in figure 1, a kind of compact closed-loop resonator based on surface plasma, including an annulus 1 and hollow Metal grating 2, described metal grating 2 includes the grating 21 of one or more, one end of described grating 21 and the inner circle phase of annulus 1 Connect, the other end points to the center of circle direction of annulus 1, and points to the hollow circle that the grating one end in annulus 1 center of circle surrounds metal grating 2 Gap 22 is that is to say, that grating 21 extends certain length to center of circle direction, and reserves near the center of circle between a small circular Gap forms hollow circular gap 22.Metal grating 2 includes the grating of one or more, and grating is along the inner circle circumference cycle row of annulus 1 Row.
