Mathematical model of an open two-mirror resonator with a traveling wave focusing

The results of mathematical modeling of an open resonance system as two confocal mirror reflectors with an aperture of the circumferential form are submitted. The excitation implements the conformal phased antenna arrays allocated on one of mirrors and forming a quasiplane wave propagated in the direction of other mirror. The reflected spherical wave is focused in the center of the resonator and forms the unidirectional electromagnetic field burst. The resonator is intended for the creation and investigation of artificial plasmoids. The examples of mathematical modeling of resonant process are submitted. The selection of resonator optimal geometry is considered.
