Interaction between mixture burning plasma and electromagnetic wave in the atmosphere

Direct integration method (DI) of FDTD is used to study the scattering characteristic of three dimensional plasma-cloaked targets. By simulating the interaction between mixture burning plasma and electromagnetic wave, the effects of plasma parameters on the radar cross section (RCS) are analyzed. The results indicate that plasma cloaking can greatly reduce RCS of three dimensional plasma-cloaked targets. According to the needs of a new experiment in which chemical mixture is used to generate plasma, DI method is also used to research the RCS of a plasma-cloaked slab. Finally, the numerical result is compared with the experimental result.
