“…In the present paper we obtain a closed-form solution for the limiting case of very small slot width, that is, a << d, h, h, h cos 0 i. While the results obtained may be applied directly to the design of efficient reflection grating polarizers for E polarization [Jull and Heath, 1980]., our objective is a better understanding of blazed diffraction gratings for applications such as multipath interference suppression. It is found, for example, that for this grating, specular reflection may be eliminated with a 'generalized Bragg condition,' which reduces to the familiar Bragg condition when only two scattered orders propagate.…”

The scattering of a plane H-polarized wave from a grating composed of narrow grooves in a perfectly conducting surface is investigated theoretically using conformal transformation techniques. The theory is exact in the limit a/d --• 0, where a is the slot width and d is the grating period, and remains valid for practical values of a/d. A necessary condition is derived for the elimination of the specularly reflected wave. When only the -1 and 0 order space waves are present, this condition becomes just the well-known Bragg condition. Phys., 9, 1509-1515. Tseng, D. Y.

“…Diffraction gratings are currently attracting interest as millimeter-wave components. Potential applications are to polarizers, frequency multiplexers and scanners, and to multipath interference suppression [Jull andHeath, 1978, 1980. A popular reflection grating profile consists of rectangular grooves, as illustrated in Figure 1.…”
