From: Radial Photonic Crystal for detection of frequency and position of radiation sources
Real part of the E-field map of a point source placed inside the RPC shell (in the inner cavity) and radiating at a frequency f = 3.8 GHz (q = 3 mode): (a) analytical simulation; (b) ab-initio simulation; (c) measurement results.
Field scale is normalized with respect to the extreme values in each plot.
