Transmission Characteristics of Electromagnetic Waves in Plasma Photonic Crystal by a Novel FDTD Method

摘要

Plasma photonic crystal (PC) has been attracted much attention due to their new particular characteristics in which electromagnetic waves with frequency below plasma frequency can propagate through it. In this paper, we analyze the transmission characteristics of electromagnetic waves for two types of plasma PC-the one with plasma rods arranged in vacuum periodically and an antiparallel one for the second type. A novel Finite-difference time-domain (FDTD) formulation for plasma is derived, the high accuracy and efficiency is conformed by comparing the reflection and transmittance coefficients of electromagnetic waves through a collision plasma with Z transform method.
