In my application, the two fields have an overlap of 90% but when I look at the fields it looks like their overlap is close to 0. This is because on one field, the amplitude is very high around an area so it looks like there is no field all around because of the normalization. I would like to normalize the two fields with the same maximum amplitude, so I can compare them visually.&lt;\/p&gt;&lt;p&gt;I tried a simple example with a fiber, a source with the fiber TE mode and a monitor just next to it. When I double the amplitude of my source, the amplitude on my field also double, which is normal. I tried to normalize the 2 fields by dividing the amplitude with the power source, but it doesn&#8217;t work, I don&#8217;t have the same maximum amplitude. Of course here I know that I just have to divide the amplitude by 2, but in my real application I want to compare 2 different field from 2 different simulations, so I want to know with which value I need to normalize.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-387836","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello,I want to compare two electric fields and calculate their overlap.
