title = "Electromagnetic absorption by metamaterial grating system",
abstract = "Total absorption of electromagnetic waves is demonstrated in a system composed of zero-order metamaterial grating and rearward metamaterial wall. The grating and the wall are separated by an air gap. Two mechanisms are shown to account for this absorption. The first one is due to the existence of standing waves in both the grooves of the grating and the air gap. These standing waves trap the electromagnetic waves and induce an oscillating surface charge density on the grating surface. The second one is due to surface plasmons at the interface between the air gap and metamaterial wall, the width of the air gap is a key parameter for the total absorption.",
