2 is a flowchart of a method for automatically setting a mobile phone ringing mode according to an environment according to an exemplary embodiment of the present invention. As shown in FIG. 2, a step of setting a mobile phone menu according to an environment (S1) and a menu is set is shown. A step S2 of transmitting a transmission wave from a mobile phone to a reverse channel, a step of receiving a reflected wave of the transmission wave from a mobile phone transmitting the transmission wave (S3), a transmission wave transmitted from the mobile phone and the received Measuring the power ratio and phase change of the reflected wave (S4), calculating the dielectric constant and permeability of the surrounding materials of the mobile phone from the power ratio and phase change (S5), and surrounding the mobile phone from the dielectric constant and permeability values obtained through the calculation Recognizing the environment by identifying the substance of the substance (S6) and the step of operating as a menu according to the user's setting corresponding to the environment (S7) There is off.
The transmission wave is a wave in which the terminal transmits data to the base station, and the transmission wave is used to inform the base station of the current position or reception quality status of the terminal. In addition, when the transmission wave is transmitted, the reflected wave refers to energy in which a predetermined energy is fed back to the terminal when it is transmitted through the medium.

If the mobile phone menu is set according to the environment in which the mobile phone is placed and then the mobile phone is moved to the set environment, the transmission wave is transmitted from the antenna of the mobile phone to the reverse channel. Transmitting a transmission wave from a mobile phone reaches a material in the vicinity of the mobile phone, and the mobile phone receives the reflected wave of this material with respect to the transmission wave.

)가 물질의 표면에 입사되는 경우, 상기 입사에너지는 투과에너지(

)와 반사에너지(

일반적으로 전자파 에너지 흡수는 물질 내부의 굴절률(Index of Refraction of Material: 굴절률은 에너지 전파 상수(Propagation Constant)에 의하여 얻어진다)에 의하여 주어지는데 이것은 두 복소값인 전기적인 값인 유전율(Permittivity,ε )과 자기적인 값이 투자율(Permeability, μ)에 관련된 값으로 표현된다. 복소 유전율 및 복소 투자율은 진공상의 복소 유전율(ε₀ =8.854×10^-12 F/m)과 복소투자율 (μ₀=4π×10^-7 H/m)에 대한 비값으로 아래와같이 표현된다.

ε/ε₀ = εΥ = εΥ - jεΥ
μ/μ₀ = μΥ = εΥ - jε
이러한 복소인자들을 가진 고분자 물질이 전자계 (electrical and/or magnetic field)안에 놓여 있을때 분자가 활성화되어 전자계 형태의 에너지를 열에너지로 변환시키면서 전자파를 흡수하게 되는 것이다. 전자파가 임피던스, Z ₀을 가진 자유공간(자유공간의 임피던스는 377Ω으로 고유값이다.)을 떠돌다가 임피던스, Z ₁을 가진 유전적 또는 자기적 재료의 표면을 만났을 때 일부의 반사가 일어나게 된다. 이때의 표면에서의 반사율(R)은 아래의 식으로 얻어지게 된다.

만일 무반사를 얻으려면 반사율(R)이 0이 되어야 하고 이것은 Z₀ = Z₁ 임을 뜻한다. 이러한 조건은 아래의 결과에 의하여 얻어진다.

매질의 표면을 통과한 전자파는 매질의 내부를 통과하게 되는데 이때의 전자파의 흡수는 재료의 유전율 및 투자율과 아래와 같은 관계를 갖는다.

흡수된 에너지 ∝

완벽한 흡수재료는 ε₁ 는 μ₁ 와 동일한 큰 값을 가지며 가능한 한 얇은 두께를 가져야 하나, 불행하게도 전자파의 주파수 대역에서는 μ₁ 의 값이 ε₁ 과 동일할 수가 없다. 결국, 이러한 문제를 극복하기 위해서는 특별한 설계와 재료의 개발이 필요하게 된다.
일정한 두께를 갖는 평판에 입사되는 전자파의 에너지 중 반사되는 전자파의 비율은 반사율(R)이라 정의되고 투과되는 에너지의 비율을 투자율(T)이라고 정의된다.
이러한 전자파의 반사율은 아래와 같이 dB로 표현이 된다.

즉, 물질의 유전율과 투자율은 물질에 따라 그 값이 다르기 때문에 유전율과 투자율을 알면 어떤 물질인지 알 수 있다.
이와 같이, 휴대폰이 유전율과 투자율을 통해서 어떤 물질인지 판별하기 위해 휴대폰은 주로 일상생활에서 사용되는 물질들의 유전율과 투자율 값을 저장하고 있으며, 또한 상기 입사 에너지와 반사 에너지를 통해 유전율과 투자율을 계산하는 알고리즘 역시 프로그램화되어 제어부에 구동된다. 따라서, 상기 계산 방법으로 반사파를 전송한 물질의 유전율과 투자율을 알아내어 휴대폰 주변에 어떤 물질이 놓여져 있는지 주변 환경을 인식하고 그 환경에 대해 사용자가 지정해 놓은 벨 종류 또는 화면상태로 자동 설정된다. At this time, the mobile phone should be able to measure the power strength and phase of the transmitted wave and the reflected wave transmitted from the antenna. The power of the reflected wave to the transmitted wave entering the antenna of the mobile phone is attenuated by the power intensity of the transmitted wave and a phase shift occurs. It is used to calculate the permittivity and permeability of the material transmitting the reflected wave.
The formula for calculating the permittivity and permeability developed below is known, which is described in the capacities and dielectrics of physics learned in high school or university, as in Chapter 25 of College Physics, published in 2002 by the College Physics Reorganization Committee. The present invention cites formulas for calculating these known permittivity and permeability.
If the incident energy (

) Is incident on the surface of the material, the incident energy is transmitted energy (

) And reflected energy (

Are divided into The reflectance R may be obtained through the incident and reflected energy, and the impedance of the dielectric or magnetic material may be obtained using the reflectance. Eventually, the dielectric constant and permeability of the material are obtained through the impedance.
In general, electromagnetic energy absorption is given by the Index of Refraction of Material (refractive index is obtained by the Propagation Constant), which is two complex electrical values, Permittivity (ε) and Magnetic values are expressed in terms of permeability (μ). The complex permittivity and complex permeability are expressed as follows as ratios for the complex permittivity (ε ₀ = 8.854 × 10 ⁻¹² F / m) and the complex permeability (μ ₀ = 4π × 10 ⁻⁷ H / m) in the vacuum.
(Equation 1)
ε / ε ₀ = εΥ = εΥ- j εΥ
μ / μ ₀ = μΥ = εΥ- j ε
When a polymer material having such complex factors is placed in an electric and / or magnetic field, molecules are activated to absorb electromagnetic waves while converting energy in the form of electromagnetic field into thermal energy. Some reflection occurs when electromagnetic waves wander through free space with impedance, Z ₀ (the impedance of free space is eigenvalue of 377 Hz) and encounters the surface of a dielectric or magnetic material with impedance, Z ₁ . The reflectance R on the surface at this time is obtained by the following equation.
(Equation 2)

here,

to be.
If no reflection is to be obtained, the reflectance (R) must be _zero, which means that Z ₀ = Z ₁ . These conditions are obtained by the following results.
(Equation 3)

The electromagnetic waves passing through the surface of the medium pass through the inside of the medium, and the absorption of the electromagnetic waves is related to the dielectric constant and permeability of the material as follows.
(Equation 4)
Absorbed energy ∝

A perfect absorbent material should have ε ₁ as large as μ ₁ and as thin as possible, but unfortunately the value of μ ₁ cannot be equal to ε _{1 in} the frequency band of electromagnetic waves. As a result, overcoming these problems requires the development of special designs and materials.
The ratio of the reflected electromagnetic waves among the energy of the electromagnetic waves incident on the flat plate having a constant thickness is defined as the reflectance (R), and the ratio of the transmitted energy is defined as the permeability (T).
The reflectance of these electromagnetic waves is expressed in dB as follows.

In other words, the dielectric constant and permeability of a material varies depending on the material, so knowing the dielectric constant and permeability can tell what kind of material it is.
As such, the mobile phone stores dielectric constants and permeability values of materials used in everyday life, and also calculates the dielectric constant and permeability based on the incident energy and the reflected energy. The algorithm is also programmed and driven by the control unit. Therefore, the dielectric constant and permeability of the material transmitting the reflected wave are found by the calculation method to recognize the surrounding environment of what material is placed around the mobile phone, and automatically set to the bell type or screen state designated by the user for the environment.

For example, if a mobile phone user selects the bell type of the mobile phone menu according to the environment by ringing on the desk and vibration in the pocket, and places the mobile phone on the desk, the power ratio and phase shift of the transmission wave transmitted from the antenna of the mobile phone and the reflected wave thereof are changed. Calculate permittivity and permeability. The calculation results are the dielectric constant and permeability of the desk, which recognizes that the phone is on the desk and automatically sets the bell type to ringtone. However, moving a cell phone into the pocket changes the power ratio and phase shift of the transmit and receive waves, which in turn alters the permittivity and permeability. The permittivity and permeability at this time become the permittivity and permeability of the material corresponding to the pocket, and the bell type is automatically switched from the ringtone to the vibration.

As described in detail above, in the present invention, when the bell type or the screen state is selected according to the location of the mobile phone, the bell type or the screen state is automatically set without the user's operation when the location of the mobile phone is changed. It is effective to immediately respond to frequent changes in the environment around the mobile phone.

In particular, when the user changes the location of the mobile phone has the effect of reducing the inconvenience of having to change the bell type or screen state every time.
