The beam envelope method in recent Comsol 4.3b is really impressive. I have a general question about the applicable area of this method. I assume this method can be applicable to any miu and epsilon tensor, such as gyrotropic, anisotropic materials, since the Helmholtz equation is general. Is this correct?

Also can I set the permittivity or permeability of the material as a function of device location, or time, in the material settings?

Thanks! :-)

I have a problem which is almost the same as here. I want a plot of the real and imaginary part of the relative permittivity as a function of the wavelength.
