电荷在透明材料表面产生电磁波，物理上抛起灰尘并将其震荡出材料边缘。
The charge creates a wave over the material's surface that physically lifts the dust and tosses it over the edges.
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。
Most of electromagnetic wave are reflected by the surface of the metal bulk material, and the transmission can be neglected.
首先介绍了基片集成波导(SIW)这一新技术，并用表面电流理论解释了电磁波在SIW中的传输模式。
A new technique called substrate integrated waveguide (SIW) is presented in this article, and then wave modes in the SIW structures are explained by using surface currents theory.
