Abstract

In order to simulate the communication signals attenuation, the model of plasma sheath is based on the layer theory and the modified double exponential model in blackout. The results of simulation show that: The attenuation constant reaches a peak value when the angular frequency of communication signal is equal to the natural angular frequency of the plasma, and the different collision angular frequency of plasma has different the peak value of attenuation. In addition, the peak value and bandwidth of attenuation is a contradiction. As electron density increases, the attenuation constant increases rapidly. When the temperature is below 1000K, the attenuation constant increases rapidly, and then reduces slowly.
