MICROWAVE PRAPOGATION IN A MAGNETIZED PLASMA
Abstract
Most microwave transmission experiments have been designed to investigate characteristics when the direction of propagation is perpendicular to the steady magnetic field. This investigation is concerned with attenuation and transmission characteristics when the direction of propagation is parallel or antiparallel to the direction of the steady magnetic field. There are two possible advantages to using this propagation direction. Firstly, relatively low microwave frequencies may be used, since by courtesy of the whistler mode, transmission may occur at frequencies below the plasma frequency. Secondly, under certain circumstances, very hgh values of the refractive index may be obtained. This means that the microwave phase velocity may become comparable with the electron thermal velocities and leads to the possibility of measuring electron temperatures. (Author)
