耦合模理论计算。原文见Plasmon-induced transparency based on a triangle cavity coupled with an ellipse-ring resonator(coupled-mode theory from Plasmon-induced transparency based on a triangle cavity coupled with an ellipse-ring resonator)

此代码用于进行线型激光谐振腔的稳定性判断及谐振腔内激光模式半径的计算。(This code is used for the stability of linear laser resonator and the calculation of laser mode radius in resonator cavity.)

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)

微波滤波器相位加载问题研究很透彻的文章，详细介绍了加载相位形成的原因和解决办法，是专业必读文章
