A simulation procedure to examine the backscattering radar cross-section (RCS) of a hypersonic object with plasma sheath is presented. Computational fluid dynamics tool is adopted to resolve the distributions of electron density and atmospheric temperature, and then the complex dielectric constant of plasma sheath are found. Volume-surface integral equation method is employed to extract the backscattering...
A one-dimensional fluid model has been used in this paper for studying the characteristics of energy and angular distributions of electrons and heavy particles under the one-atmosphere pressure coupled by dual-frequency excitations. Using the current balance equation instead of poisson equation for solving the electric field equation. The results show that: the high-frequency source determines the...
In the eddy current brakes, the magnetic field can be produced by excitation winding systems or by permanent magnets. According to the difference of flux sources, the eddy current brakes could be divided into three types: the electric excitation eddy current brakes, the permanent magnet eddy current brakes and the hybrid excitation eddy current brakes [1]-[2]. The hybrid excitation eddy current brakes...
