Abstract

An investigation isundertaken to study the transmission of the electromagnetic waves through inhomogeneous over-dense plasma. The transmission is due to the excitation of the surface modes of plasma or plasmons. The construction of the plasma is in such a way that the charge density of the plasma linearly increases and passes through its critical value and then linearly decreases. The dissipative effects are considered for the plasma. The amplitude of the electromagnetic waves and the reflection coefficient are calculated and then the distribution of the electric field amplitude of the entire structure is obtained and discussed. In this way, itis shown that the considered structure facilitates the anomalous wave transmission through over-dense plasma medium.
