Terahertz radiation is long-wavelength, so the structures I want to study have dimensions of the order of 1000 microns. This creates resolution restrictions. I use a resolution of about 0.05 pixels per micron in my simulations. I read that for example copper, even 10 pixels per micron is too low a resolution, as an error appears about fields is NAN or infinity. How to solve the situation?
