Hi,
i am simulating using FDTD.
my computational domain is 1D with a dielectric medium at the center. i have a Gaussian input that moves from left to right of the medium. i put a probe both at the left and right of the medium and saved the fields at these locations at every time step.
does anyone know how to calculate the input/output power from the fields i saved using Fast Fourier Transform (FFT)?
i'm actually doing an FDTD paper wherein FFTs are performed on the incident and output fields to get their power.
tnx
