Abstract

Electromagnetic wave attenuation characteristic in reentry plasma was analyzed. Based on non-decreasing total amount of plasma electron on radiation aperture, a method of reducing electromagnetic wave attenuation by changing electron density periodically along direction of polarization was presented. For electron density with uniform distribution and actual reentry experiment distribution, electromagnetic wave propagation was simulated by using transmitting and receiving antennas. Electric field intensity of electron density with uniform distribution and periodically changed distribution was simulated. The electromagnetic wave attenuation for uniform distribution and actual reentry experiment distribution was calculated, and the attenuation for primary distribution and periodically changed distribution was compared. The simulation results show that the electromagnetic wave attenuation is decreased, and the electromagnetic wave propagation characteristic is improved by changing electron density periodically along direction of polarization.
