Abstract

The transmission of electromagnetic waves across a thin plasma layer whose width is comparable to the wavelength of an incident wave is studied. The transmittances of transverse electric and transverse magnetic modes for both underdense and overdense plasmas are obtained as a function of the angle of incidence. It is thought that the significant reduction of transmittance in overdense plasma's transverse magnetic modes is caused by the excitation of the electron plasma wave on the plasma resonance layer.
