Perfectly blazed reflection gratings with rectangular grooves

Perturbation theory for a cavity resonator with a bi‐isotropic sample: Applications to measurement techniques

“…Physically, the proposed method of the nonreciprocity parameter measurement is based on the coupling between two orthogonal modes when a bi-isotropic sample is present inside a resonator. Indeed, if a sample is positioned in a z-axis-directed electric field, a zdirected magnetic field will be generated due to the constuitive relations (1). When the sample is nonreciprocal, then the magnetic field will have a z-component, which is proportional to x and is in phase with the original electric field.…”

Bio-Inspired Functional Surfaces Based on Laser-Induced Periodic Surface Structures

“…Equation (7) describes the condition for a constructive interference from periodic elements on a surface [59] $m\times \lambda =\Lambda \times \left(\sin {\theta }_i\times \cos \varphi +\sin {\theta }_m\right)$ with the incident angle θ i , the diffracted angle θ m for order m, the orientation φ of the ripple pattern relative to the plane of incidence, the wavelength λ and the groove spacing Λ (Figure 9a). These parameters control the possible presence and direction of various orders.…”

A Modal Theory Solution to Diffraction from a Grating with Semi-circular Grooves

“…The perfectly conducting lamellar profile is the most suited to a modal method solution and has received attention from a theoretical viewpoint from Deriugin [2], Wirgin [3], and Maystre and Petit [4] . Its ease of computation and its interesting behaviour have resulted in other recent studies [5][6][7][8][9][10][11] . More recently, eigenvalue modal techniques have been established to account for the dielectric lamellar grating [12,13] and its finitely conducting counterpart [14] .…”
