RF Engineer

Hi! I want to calculate modal admittance of individual modes, it can be calculated using formula provided in the attached file. How to get current values of each mode, I want to plot the graph provided in the second figure.

First step would be to see if the Feko calculated source data would provide what you are looking for.
Add a 1V voltage source to your CMA model and plot the modal admittance. If this is not what you are looking for you will have to look into writing your own scripts. Have a look around on the forum for LUA scripting in POSTFEKO.
