I have a question related to the placement of a single z-normal monitor. I have placed a monitor(35x35x0.17um) exactly on the top of the structure(on the surface closer to the dipole source). I have made the simulation region larger(25x25x2um). And why I am getting different polar plots if i placed the monitor a little far from the structure surface and&nbsp; far from dipole source. How did i know which plot is correct?&lt;\/p&gt;&lt;p&gt;1) Close to the source\/on the surface(blue colour thin film)&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/18-04-2024-1713458415-Screenshot (38).png\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;Here monitor(Z2) is placed on the top\/surface of thin film.(blue layer).
