我们从理论上和实验上证明，当在等离子体表面前放置一个亚波长衍射光栅时，电磁波可以被过密等离子体完全吸收。吸收是由于表面等离子体波（等离子体激元）的耗散，所述表面等离子体波（等离子体激元）已经被衍射电磁波的渐逝分量共振地激发。开发的理论模型允许一个确定的条件下，总吸收。
We show both theoretically and experimentally that an electromagnetic wave can be totally absorbed by an overdense plasma when a subwavelength diffraction grating is placed in front of the plasma surface. The absorption is due to dissipation of surface plasma waves (plasmons polaritons) that have been resonantly excited by the evanescent component of the diffracted electromagnetic wave. The developed theoretical model allows one to determine the conditions for the total absorption.
