Properties of Terahertz Wave Propagation in Inhomogeneous Plasma Sheath

Abstract

Abstract: The communication blackout usually happens when the hypersonic vehicles voyage in the near space. According to the data provided by radio attenuation measurement C (RAM C) voyage experiment, two models of inhomogeneous plasma sheath were established after dividing the near space into two spatial layers to build two mathematical models. The principle of interaction between plasma and terahertz wave was analyzed through numerical calculation, getting the properties of terahertz wave propagation in plasma sheath. The simulation shows that the terahertz wave frequency band selected as communication frequency band used in near space can solve the problem of communication blackout. The result of simulation can be provision of reference for design of communication frequency-band used in the near space hypersonic vehicles.

Key words: plasma sheath, terahertz wave, near space, hypersonic vehicles
