Hi all,
I am a beginner at working with MEEP software and FDTD simulations. I
wanted to simulate the radiation pattern of an antenna with a long
conductor kept nearby. I tried to modify the Near to Far-field example
to obtain the result.
While defining the geometry I added a metallic block which can be
considered as the long conductor(1m vertically below the source)...the
source is at the middle (0,0) as in the example : (a=1m considered)
geometry = [mp.Block(mp.Vector3(mp.inf,0.001),
center=mp.Vector3(0,1),
material=mp.metal)]
In the simulation, the near field box is 4m width and height around the
source(full cell size as in the tutorial example) ...the rest of the flux
is obtained from the far-field calculations.
I would like to increase the distance of the conductor from the source..but
can I increase it beyond the near field box? Can I place it in the
far-field region? Or should I increase the size of the near-field box and
place the conductor within?
Kindly advise me on the same.
