Terahertz electromagnetic wave propagation in uniform magnetized plasma
摘要
Abstract
The propagation of terahertz electromagnetic wave in uniform magnetized plasma is investigated. The relationship among terahertz wave attenuation, phase shift and the plasma density, collision frequency, wave frequency and magnetic field strength are obtained. The attenuation and phase shit increase with the increasing of plasma density, and the attenuations first increase to peak value and then decrease with the increasing of collision frequency. When the magnetic field strength increases, the value of peak increases and the peaks move toward lower collision frequency. And when the collision frequency is close to wave frequency, the attenuation of right polarization wave reaches a maximum value. With the increase of wave frequency, the attenuation decreases, and phase shift firstly increases, and then decreases.关键词
