Questions on the tutorial phased antenna patch array

Post by thinkless » Mon 04 Apr 2022, 04:23

Hello, everyone.
I am now trying to realize the numerical example "phased antenna patch array" with my own FDTD code. As I can see in the script given by openEMS, there is the code :

Code: Select all

% capacities for port 2 and 3 to shift the far-field pattern
C2 = 0.2e-12;
C3 = 0.2e-12;
So although the capacitance is variable, in FDTD simulation fixed capacitance value is used, is that right?
Second question, to obtain the same result as the given file, do I just use a single Gaussian pulse voltage source for port 1? Or use current source and specify the current as in code:

Code: Select all

I_out(1,1) = 1e-3;
Thank you in advance.
