摘要: In this chapter we will consider the theoretical analysis and properties of doubly periodic diffraction gratings (“bigratings”). Our interest in these structures has been stimulated by two factors. Firstly, their study represents a natural extension previous work on mono-periodic structures. Secondly, HORWITZ [7.1] suggested use metallic grids as selective filters (heat mirrors) solar energy absorption. Of course such devices have application far infrared spectroscopy beam splitters [7.2], [7.3–5] reflecting elements Fabry-Perot interferometers [7.5–10]. Similar applications exist field microwave engineering [7.11.13].
