Properties of C-Band Wave Propagation in Plasma Sheath with Different Incidence Angle

Propagation characteristics of oblique incidence terahertz wave through non-uniform plasma

“…Before we start to analyze the propagation characteristics of the THz wave through an inhomogeneous plasma, the validity of the method adopted in this paper is verified by comparing the results obtained by our method with those obtained by an analytical method. [35] The propagation characteristics of THz waves with different incident angles in a homogeneous plasma slab are taken into consideration.…”

“…The plasma density stemmed from the reentry hypersonic flight in the stagnation region could reach 10 21 m −3 and the plasma frequency corresponding to this electron density can reach 0.28 THz. [24] In the following simulations, the Gaussian electron density profile is chosen to stand for the variation of electron density, which corresponds to the non-uniform plasma flow field around the hypersonic aircraft at a high altitude of space [35] n e (y) = n emax e −α 2 1 y 2 , y 1 y 0,…”

“…To describe the distribution of the electron density in an inhomogeneous plasma, the Gaussian profile is introduced which corresponds to the flow field around the hypersonic aircraft at a high altitude of space. [35] The rest of this paper is structured as follows. In Section 2, the physical model of the propagation problem is given, with a brief description of the method used in solving the problem under study.…”
