Prad from nf2ff

Post by florianb » Thu 07 May 2020, 09:53


I have simulated a horn antenna based on the Tutorial

Although the simulation result is agreeing with my expectations, I have noticed that the radiated Power from nf2ff is ~1dB larger than the incoming power of the input port (10*log10(nf2ff.Prad/port.P_inc(port.f == f0)) gives 0.95dB). What could be an explanation for that? Did I disregard any constraints in my simulation script?
