Dear Steven G:
Thank you very much for you help.But I still have some questions:
What means "CW"? I do not know where to compute the flux spectra? Is it in the dielectric near the boundry of dielectric-air? How to define a bunch of random current sources? Is it a Gaussian-pulse?
In APL. 87.203508, there is a absorption coefficient. How to embodiment it in meep?
