In this paper, the results of analytical and numerical investigation of whispering gallery modes (WGMs) in parallel‐plates‐type cylindrical anisotropic and isotropic dielectric resonators are presented. The dependence of the WGMs' resonant frequency, Q‐ factor, and energy‐filling factor upon resonator parameters for the wide range of the azimuthal index has been studied numerically. The optimization of resonator parameters for sensing applications is discussed. © 2004 Wiley Periodicals, Inc.
