In a model with vertical incidence of plane electromagnetic wave into plasma slabs with metal underlay, the attenuation of electromagnetic wave and reflected power are deduced.
采用垂直入射具有金属衬底的均匀等离子体模型，对不同入射频率的电磁波的衰减以及总出入射功率比进行了数值模拟。
Most of electromagnetic wave are reflected by the surface of the metal bulk material, and the transmission can be neglected.
对于金属块体材料，电磁波的大部分能量在金属的几何表面被反射回去，其透射忽略不计。
Then based on electromagnetic theories, incident wave is not totally reflected back, there is also a refractive wave in the second medium.
但由电磁场理论，入射波并不是简单地全部返回原媒质，而是要在第二种媒质中存在一折射波。
