Study on electromagnetic wave propagation characteristics of inhomogeneous magnetized plasma with different incidence angles based on ISMM

Since the traditional scattering matrix method (SMM) generates singular matrix in the calculation process, this paper calculates the reflection coefficient and transmission coefficient of electromagnetic wave in plasma turbulent medium at different incident angles based on the improved SMM (ISMM) and one-dimensional magnetized plasma turbulence model, and analyzes the propagation characteristics of electromagnetic wave in inhomogeneous magnetized plasma. The results show that the turbulent flow greatly affects the motion of electrons in the plasma sheath, and the energy attenuation increases during the motion, so the transmission coefficient of the 0−35 GHz increases. On the other hand, the increase of the external magnetic field has opposite effects on the propagation characteristics of the left-circularly polarized wave and the right-circularly polarized wave, because in the left-circularly polarized wave, the rotation direction of the left-circularly polarized wave is exactly the same as the rotation direction of the electron, and the right-circularly polarized wave is opposite. With the increase of incidence angle, the propagation distance of electromagnetic wave in plasma turbulence increases, resulting in more electromagnetic wave energy being absorbed. In addition, considering the inhomogeneous magnetization, the transmission coefficient of right-handed circular polarization of electromagnetic waves in the 0−35 GHz band is larger. These results provide a theoretical basis for studying the propagation characteristics of electromagnetic waves in turbulent media of inhomogeneous magnetized plasma.
