Summary: | Abstract
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”. |
