两种湿沙颗粒电磁散射特性求解模型的比较研究
Comparison Research Between Two EM Scattering Models for Wet Sand Particle
摘要
Abstract
Based on the equivalent sphere model and the coated sphere model, the EM scattering properties of wet sand are calculated, and the results derived from these two models are made. The results show that there are significant differences between these two models, and if we considered the dispersion effect, the difference even up to ten times. In addition, we also concluded that with the increasing of sand moisture content, the results from these two models show different changing trends. So we must carefully choose the calculation model when calculating the EM scattering of wet sand particle.关键词
