A Solution to the Propagation of Electromagnetic Wave in Plasma Sheath Using FDTD Method

摘要

An auxiliary differential equation finite-difference time domain (ADE-FDTD) methodology was used here to study the propagation of electromagnetic wave through a plasma sheath The reflection and transmission coefficients calculated by ADE-FDTD were compared with the analytic ones.The result shows an excellent agreement.Then,ADE-FDTD was used to resolve wave propagation in plasma sheath of RAMC flight,and the FDTD results agree with the date measured by RAMC flight.
