| Abstract: |
| Objective To study the attenuation characteristics of terahertz wave in inhomogeneous magnetized plasma. Methods The attenuation characteristics of terahertz wave inhomogeneous magnetized plasma with oblique incidence were analyzed with the WKB approximation method. Results The attenuation increased with the increase of the incident angle, and decreased with the increase of the collision frequency. When the intensity of external magnetic field increased, the maximum attenuation moved towards the higher frequency of terahertz wave. The attenuation increased with the increase of peak value of electron density. Conclusion The adscititious magnetic field intensity, the plasma electron density and the collision frequency can be adjust to change the attenuation process of THZ wave propagation in plasma to provide a valuable reference for the plasma stealth technology. |
