Dear all,

I'm using COMSOL to simulate a TE waveguide with a ZIM slab between to layers of air. I want to define the permeability and permittivity in the ZIM region using Drude mode where:

mu = epsilon = 1 - (wp / w(w+i*gamma))

notice that w = the angular freq. and wp = plasma freq.
Q1 : I defined my model as in here: (www.dropbox.com/s/jxwbakt6ib5l97t/EV_1_%282%29.mph)
but still I have an error in the units?! why is that happening?
Q2 : Is there any other way to define the Drude mode?
Q3: Why I can't draw the transmission and reflection using 1D plot?

Thanks.
