消逝波在导电媒质中对电磁力的增强效应
Enhancement of electromagnetic force on conducting slab by evanescent wave
电磁消逝波的最大特点是波传播常数虚部不为零,分为有损耗的衰减模式和无损耗的凋落模式,在凋落波的作用下,导电媒质中因为传导电流的存在,其中衰减模式的电磁场对传导电流的切向力出现有趣的增强现象。
In this paper, we introduce an interesting phenomenon in conducting medim. The enhancement of tangential electromagnetic force by evanescent field from dielectric medium exist on inducing currents. In the air layer, the fields is belong of decaying wave. And in conducting medium below the air layer, the fields is evanescent wave. The force come from the interaction between evanescent wave and inducing current.
