Paper Abstract

The possibility of the describing of electromagnetic eigenmodes (WGM) or a spherical particle by geometrical optics is shown. The estimations of surface deformations influence on a quality-factor (Q-factor) or resonant eigenmodes are carried out. The selection of resonant electromagnetic modes of the particle caused by surface deformations is shown. In ideal sphere the question on a competition of resonant modes will be decided always for the benefit of high quality electromagnetic modes usually be of low orders. But if the surface of a liquid particle is deformed when the advantage become higher order modes, which posses smaller values of Q-factor, but more resistant to deformations of particle surface.
