Linear coupling of electromagnetic waves in inhomogeneous weakly-ionized media
An account is given of the current state of the problem of linear coupling between electromagnetic waves. Conversion effects are discussed for waves in the radio, optical, and x-ray frequency rangesExpand

Linear wave interaction in a plasma with an inhomogeneous magnetic field
The linear interaction of waves in the region where the geometrical-optics approximation is violated is analyzed qualitatively on the basis of the Budden--Kravtsov equations that describe theExpand

Linear wave conversion in an inhomogeneous plasma with magnetic shear
Linear conversion of electromagnetic waves is studied for a plasma with a weak density gradient and magnetic shear. The amplitudes and phases of the geometric optics waves transmitted through theExpand

Collective electron-positron annihilation
Abstract The phenomenon of collective spontaneous annihilation of a magnetized electron-positron plasma is predicted. Like superradiance in systems with discrete energy spectra, collectiveExpand
