EM Wave Propagation Analysis in Plasma Covered Radar Absorbing Material

This book focuses on EM propagation characteristics within multilayered plasma-dielectric-metallic media. The method used for analysis is impedance transformation method. Plasma covered radar absorbing material is approximated as a multi-layered dielectric medium. The plasma is considered to be bounded homogeneous/inhomogeneous medium. The reflection coefficient and hence return loss is analytically derived. The role of plasma parameters, such as electron density, collision frequency, plasma thickness, and plasma density profile in the absorption behavior of multi-layered plasma-RAM structure is described. This book provides a clearer picture of EM propagation within plasma. The reader will get an insight of plasma parameters that play significant role in deciding the absorption characteristics of plasma covered surfaces.

Provides detailed analytical description of EM propagation within plasma covered multilayered structure Includes several colored illustrations for providing a clear picture Presents parametric analysis of EM propagation within plasma covered structure in tabular form that allows the reader to infer quickly the role of parameter in reducing scattering effect Includes supplementary material: sn.pub/extras
