# Eigenfrequencies and Q factor in the geometrical theory of whispering-gallery modes

## Abstract

It is shown that the quasi-geometrical approximation permits a quite accurate calculation of the eigenfrequency spectrum of axially symmetric dielectric resonators with whispering-gallery modes and also gives expressions for the radiative Q factor and Q factor related to surface losses. (resonators. modes)
