“…Unlike echelette-type gratings and corrugated mirrors, a short-circuited waveguide-type diffraction grating may be used to create a controllable element in an electronic device [5][6][7]. Wave beam diffraction on a two-dimensional periodic grating of short-circuited rectangular waveguides with rectangular and non-rectangular grids was studied in [8][9][10]. In [14][15][16] the nonlinear interaction of electromagnetic waves on planar metamaterials supporting trapped-mode resonance problems are considered.…”

This paper investigates nonspecular reflection of three-dimensional Gaussian wave beams from a two-dimensional periodic grating of short-circuited rectangular waveguides. 'Orthogonal' beam reflection from a periodic structure has been examined. The correlation of reflection rates in terms of power and the length of short-circuited waveguides has been estimated for specular and nonspecular beams. The relation of the reflected beams' directional pattern in the far field to the array and incident beam parameters has been investigated. The splitting effect of the reflected beams' directional pattern has been established in the case of p-polarized beam incidence. The possibility of applying a grid of rectangular waveguide sections in an electromagnetic field impulse compressor has been demonstrated. Various operational modes of the reflection grating used as a coupling element between the open-structure resonator and the transmission line have been described. The effects of directional pattern reduction and reflected beam directional pattern deformation have been established. These effects have been physically grounded. The results are presented in the form of three-dimensional directional patterns of the diffuse beam field in the far field. The calculation algorithm is based on the available solutions of the key vector problems of plane linearly polarized electromagnetic wave diffraction on two-dimensionally periodic structures.

“…In [5], the autocollimation mode is studied on one-dimensional arrays with a finite number of elements, while [6,7] deal with the problems of diffraction of E and H linearly polarized waves on reflecting arrays covered with a chiral layer. Diffraction studies of the wave beam on a two-dimensional periodic waveguide-type array with the centers of the master cells lying in the nodes of a rectangular grid are provided in [8,9].…”

This paper investigates the dispersion of a three-dimensional Gaussian wave beam on a two-dimensional periodic array of short-circuited waveguides with a beveled (nonrectangular) grid in the autocollimation mode. The correlation of reflection rates in terms of the power and the length of the short-circuited waveguides has been estimated for specular and non-specular beams. The relationship between the directional pattern of the reflected beam in the far field and the array and incident beam parameters has been investigated. Three-dimensional directional patterns have been designed in terms of the power of specular and non-specular beams in the far field. Energy characteristics and three-dimensional directional patterns have been obtained for the non-specular beam in the far field. A new algorithm for analyzing three-dimensional problems of scattering of linearly polarized wave beams on two-dimensional periodic structures is proposed. This algorithm allows the investigation of wave beams with arbitrary field distributions over the cross-section. The case of oblique incidence of a linearly polarized Gaussian wave beam on a two-dimensional periodic structure is considered. A reflective array with short rectangular waveguides is chosen as the structure. The beam pattern transformation of the scattered beam in the far field is investigated. The effects of narrowing of the beam pattern and distortion of the reflected beam pattern are detected. A physical explanation of these effects is offered. The results are presented in the form of two-dimensional and three-dimensional patterns of the scattered field of the beam in the far field.
