FDTD Analysis of Reflection of Electromagnetic Wave From a Conductive Plane Covered with Inhomogeneous Time-Varying Plasma

摘要

A finite-difference time-domain (FDTD) algorithm is applied to study the electro-magnetic reflection of conduction plane covered with inhomogeneous time-varying plasma, homo-geneous plasma and inhomogeneous plasma. The collision frequency of plasma is a function ofelectron density and plasma temperature. The number density profile follows a parabolic func-tion. A discussion on the effect of various plasma parameters on the reflection coefficient is pre-sented. Under the one-dimensional case, transient electromagnetic propagation through variousplasmas has been obtained, and the reflection coefficients of EM wave through various plasmasare calculated under different conditions. The results illustrate that a plasma cloaking system cansuccessfully absorb the incident EM wave.
