Abstract

The circular polarization of the magnetic field of the whispering-gallery (WG) modes of resonance of a dielectric disk resonator was tested in the evanescent-field region outside the dielectric material. Microwaves in the frequency range from 18 to 26.5 GHz (K-band) and the techniques of electron spin response (ESR) were used. The distribution of the electromagnetic fields was obtained with a finite element method, and it was found to be in agreement with the experimental results
