HFSS S参数问题

网友回复:

贴帮助文件中的几段话，希望对你有帮助： 
1.When solving for the S-parameters, HFSS assumes that the structure is excited by the natural field patterns (modes) associated with these cross-sections 
2.Lumped ports compute S-parameters directly at the port. 
3.HFSS solves in the frequency domain and obtains a phasor representation of the steady-state finite element field solution. Physical quantities such as the instantaneous (time domain) electric field are then obtained as derived quantities from the phasor representation 
 
 
S参数用来描述端口间能量反射和传输特性 
=[s][a],其中这里的元素都是复数，有幅度和相位，通常我们用dB作单位来得到s参数图 
其中，|bi|^2 是端口i的传输或反射功率，|ai|^2是端口i的入射功率，ai和bi的相位表示入射和反射/传输场在t＝0时的相位

S参数是根据电压关系算的，关于S参数问题，推荐楼主看看微波技术相关书籍

waveport和lumpport的s参数的定义是一样的么?
