实现微环滤波器的关键程序，包括微环，光栅，波导等模拟(This program is mainly use matlab to simulate the working process of the core components of the bandpass filter, including the microring resonator and bragg reflector, waveguide, etc)

ansys计算2个例子，可以运行的，孙涛分析电容，以及谐响应分析(Two examplses: Transient response of an electrostatic transducer-resonator ;Transient and harmonic analyses of a piezoelectric circuit)
