Abstract
It is observed that ray oscillations may be excited together with whispering gallery modes in quasioptical dielectric cavities. It is shown that as the excitation conditions change, the fields of these oscillations gradually “split off” from the fields of the whispering gallery modes whose characteristics deteriorate. The angular spectrum of ray oscillations in dielectric cavities is determined.
