I am trying to simulate a simple structure, where I have a dielectric, sandwiched between two metallic layers in time domain. I work at a single frequency, so there is no need even to define the metal dispersion here, all what I need is just to give the metal a permittivity value that is negative. When I do that in frequency domain, it works perfectly, however in time domain it gives me this error "Attempt to evaluate real square root of negative number", how can I resolve this issue ?. Thanks in advance.
