Grating Diffraction Calculator (GD-Calc ®)

GD-Calc is a MATLAB-based tool for diffraction grating simulation, which has utility for a variety of grating types and applications, e.g.: - surface relief gratings - multilayer gratings - biperiodic gratings - binary/lamellar or blazed kinoform gratings - subwavelength gratings (e.g., photonic crystals, metamaterials) - polarization gratings (e.g., form birefringence, wire-grid polarizers) - moth-eye antireflection structures (e.g. for solar cells or high-power lasers) - micro optics, nano optics, diffractive optics (e.g. phase-Fresnel structures) Many illustrative applications of GD-Calc can be found in the peer-reviewed literature by searching for “GD-Calc” in Google Scholar.
