$All About Diffraction Gratings Edmund Optics$

WebA “diffraction grating” is an optical element that imposes a “periodic” variation in the amplitude and/or phase of an incident electromagnetic wave. 1 It thus produces, through constructive interference, a number of discrete diffracted orders (or waves) which exhibit dispersion upon propagation. WebHerein, the 2D angular bandwidth broadening metasurface grating that exhibits uniform and high diffraction efficiency for the 2D FoV range is proposed. Specifically, the proposed device is designed specifically, and the diffraction efficiency of this device shows uniform efficiency of about 75% with a variance of 0.25% for the FoV range, and it ...
