The transmission characteristics of terahertz waves propagating in high-temperature magnetized inhomogeneous plasma are theoretically analyzed. The influence of physical parameters, such as the electron density, collision frequency, plasma thickness, magnetic field strength, electron temperature, and so on, on the transmission properties is considered systematically. Numerical results show that these parameters will affect the propagation characteristics of terahertz waves travelling in plasma. Especially, when the electron temperature of the plasma or the magnetic field is adjusted to an appropriate value, a sharp transmissivity peak (absorptivity valley) will be produced in the stop band. As the intensity of the magnetic field increases, the corresponding frequency of the transmissivity peak (absorptivity valley) will gradually shift to higher frequencies. The peak (valley) value will gradually increase as the electron temperature increases. These theoretical results may be used to effectively alleviate the “blackout problem”.

理论分析了太赫兹波在高温磁化非均匀等离子体中传播的传输特性。系统地考虑了电子密度、碰撞频率、等离子体厚度、磁场强度、电子温度等物理参数对传输特性的影响。数值结果表明，这些参数会影响太赫兹波在等离子体中传播的传播特性。特别是当等离子体或磁场的电子温度调整到合适的值时，会在阻带中产生尖锐的透射率峰值（吸收率谷值）。随着磁场强度的增加，透射率峰值（吸收率谷）的相应频率将逐渐向更高的频率移动。随着电子温度的升高，峰（谷）值会逐渐增大。这些理论结果可用于有效缓解“停电问题”。
