Hi,
I was trying to study the radiation from an nano-scale antenna as well as its impedance. However, the solution doesn't converge. I tried all iterative methods, unfortunately, none of those actually worked.
I tried to use the Gauge fixing for A-field. it gave my an error saying that "a 0 element in the matrix". I knew I may be able to fix it by increasing the conductivity of air and other high resistance components. But I don't really want to do so, because the antenna has a really low conductivity too~10^4 S/m
Any help will be appreciated.
