A modified method of variable separation for the problem of TE wave diffraction on a diffraction grating with two-layer lines in the period

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки
The diffraction of an electromagnetic TE wave on multilayer diffraction gratings with several two-layer lines in the period was investigated. Such optical structures are employed in spectral beam combining.

Anisotropic diffraction efficiency of two-dimensionally periodic Janus microstructures

open access: yesResults in Surfaces and Interfaces
Two-dimensionally periodic Janus structures possess identical structural periods along two orthogonal directions while maintaining asymmetric contour profiles within each unit cell, enabling anisotropic optical responses that differ from those of ...

Plane wave diffraction by a rational wedge [PDF]

open access: yes, 1986
In this paper new expressions for the acoustic field produced when a plane wave source of sound is diffracted by a soft, hard or mixed soft/hard wedge whose angle can be expressed as a rational multiple of are given. The solution is expressed in terms of

Changes of the diffraction efficiency due to emulsions thicknesses in holographic gratings [PDF]

open access: yes, 2007
We analyze the behavior of the diffraction efficiency as a function of the thickness of the relief holographic grating recorded on a phase emulsion composed by rosin and bromophenol blue (BPB) dye.

A high-efficiency tunable relativistic magnetron with diffraction output

open access: yesAIP Advances
In this paper, a high-efficiency tunable relativistic magnetron with diffraction output (HTRMDO) is presented and studied numerically. To increase the tuning bandwidth and power efficiency, the outer radius of the resonant cavity and the magnetic field ...
