Calculation and simulation on plane-wave absorption characteristics of magnetized plasma

The absorption characteristics of the plane electromagnetic wave in magnetized plasma is studied by using the equivalent input impedance method. The result shows that the absorption characteristics can be primarily affected by the electron numerical density, the collision frequency, and the magnetic intensity. Different modes of electromagnetic wave are discussed and the variation of absorption property with changing parameter is given. A finite element simulation result is obtained by taking equivalent permittivity of plasma stabs in. This work explains operation parameter chosen principle and is useful for engineering application.
