Abstract

Interaction of an electromagnetic wave and an inhomogenous plasma slab with electron distribution in the form of partially linear and sinusoidal profiles is analysed to determine new reflection, absorbtion and transmission characteristics. Broadband and tunable absorbtion performance of the plasma layer accompanied with narrowband reflection characteristics is presented as the function of electron density profile parameters and external magnetic field excitation. According to the resulting performance characteristics, proposed plasma layer is found to be useful as a new absorbing layer for shielding and stealth applications.
