| Abstract: | The effective static dielectric constant of an electron plasma system in the simultaneous presence of two electromagnetic waves and a strong DC magnetic field is calculated. It is found that as the difference Δω of the two electromagnetic wave frequencies matches the plasma frequency ωρ a breakdown in screening occurs thereby increasing the plasma heating rate via the external fields due to inverse Bremmstrahlung. An application is made by considering the typical parameters of a hot plasma. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
