Is there an efficient way to simulate a 1.5m aluminum (200um rms) reflector at sub-THz frequencies?
Description: Hi there, the issue I'm having is that I've been using the LE-PO solver, but it doesn't work for lossy materials such as aluminum surfaces. I'm specifically trying to obtain a model that accounts for the surface material and surface roughness (200um for example) seen when using a horn-fed dish (single…
