Hello,
I am writing a 1D FDTD to simulate a wave propagate into aluminium thin film. Unfortunately, whenever the wave hit the metal surface, the E-field progressively increases and becomes unstable.
Would anyone know what's the program and any solution for that?
Here below are the parameters that I am using:
wavelength: 1um
n_Al: 1.35 (measured)
k_Al: 9.58 (measured)
grid size: wavelength/50
time_step: grid size / (2*c)
Thanks!!!
