FFT and FDTD
Dear friends
I have a problem with FDTD
I used method FDTD to simulate Microstrip antenna by using matlab
The propagation of the Gaussian pulse is very will
But by using FFT , I noticed that :
1- The resistances at some frequencies are negative
2- The time domain results ( like current) reached to zero at some time and then oscillated very high
