Research on the influence of dielectric material surface fidelity and finish on scattering characteristics

Based on electromagnetic field theory, starting from Maxwell's Equations, and by formula derivation, the volume integral equations of three dimensional dielectric objectives are deduced in this dissertation. By converting the volume integral equation into the matrix equation and calculate the electromagnetic current coefficient according to the matrix equation, the radar cross-sections of the three-dimensional dielectric objects can be obtained; At the same time, material sample block objects also have been studied, and error analysis has been carried out on the effect that model fidelity and surface finish have on electromagnetic scattering characteristics.
