摘 要: 电磁波具有动量,若直接使用电磁波来驱动物体,在物体的远程驱动方面将有极好的应用前景。在平面波的假设下,如果是凋落波,导电媒质中由于传导电流的存在,经过计算表明:衰减模式的电磁场对传导电流的切向力出现增强现象。
关 键 词: 微波技术;电磁切向力;消逝波;导电媒质

Abstract: Electromagnetic wave has momentums. Objects could be driven by electromagnetic wave directly, and this phenomenon has a great potential for future application in remote transmission of energy. If the incident wave is plane wave, and the conducting medium is driven by evanescent field, the force come from the interaction between evanescent waves and inducing current is enhanced.
Key words: microwave technique; tangential electromagnetic force; evanescent wave; conducing medium
