Analysis of Terahertz Wave on Increasing Radar Cross Section of 3D Conductive Model

Enhancing the frequency band of electromagnetic wave is regarded as an efficient way to solve communication blackout problem. In this paper, incident raised Terahertz (THz) and radar cross section (RCS) three-dimensional conductive model calculated simulated based on Runge–Kutta Exponential Time Differencing–Finite Difference Domain method (RKETD-FDTD). Interaction THz magnetized plasma sheath discussed. Attenuations in frequencies 0.34 3 GHz different densities are analyzed. The monostatic RCS used compare penetration while bistatic fixed study its characteristics. simulation result has almost same that without coating when reaches THz. advantages at increasing reducing attenuation demonstrated from aspects including polarizations, angles, magnetization anisotropy plasma, thickness scan planes inhomogeneous distribution plasma. It can be concluded unique applied problem interruption.
