Measurement of the attenuation of an electromagnetic wave in a bounded hot electron plasma

Under certain conditions of electron temperature and mean free path the attenuation of an electromagnetic wave incident on a vacuum‐plasma boundary cannot be described in terms of the usual complex conductivity. In a cylindrical plasma with an electron density lying between 1010 and 1012 cm−3, and a...

Zusammenfassung:	Under certain conditions of electron temperature and mean free path the attenuation of an electromagnetic wave incident on a vacuum‐plasma boundary cannot be described in terms of the usual complex conductivity. In a cylindrical plasma with an electron density lying between 1010 and 1012 cm−3, and an electron temperature of 2.2 eV measurements of the attenuation of a small amplitude wave show resonance phenomena due to interaction between the wave and the moving electrons. A theory of this resonance for the case of a plasma slab is compared to the experimental results.
