Comparing FEKO Results in .out and POSTFEKO

Hello,

I am having some trouble comparing the results that are displayed in POSTFEKO and the results in the .out file. I made a script that imports the far field values in MATLAB and when I use these complex field values (in Volts according to the .out file) and calculate the RCS in dBsm the values are different than the results I get in POSTFEKO, which look correct. The equation I'm using for dBsm is 20*log10(abs(E_theta)) (for example). Is this the same equation that is used in POSTFEKO? Thanks!

The equations are given in the Altair_Feko_User_Guide.pdf in the help folder of your installation. See section 8.6 "Far Fields and Receiving Antennas"

Thanks Mel! All I need to do is multiply the far-field values in the .out file by sqrt(4pi) and everything works out.
