GD-Calc, the Grating Diffraction Calculator, computes optical diffraction efficiencies of biperiodic grating structures comprising linear, isotropic, and non-magnetic optical media, based on a generalized variant of rigorous coupled-wave (RCW) diffraction theory. Engineers, scientific programmers, researchers, and students with an interest in optics will find GD-Calc and the accompanying documentation to be a very useful resource for diffraction grating analysis.
GD-Calc is implemented entirely in MATLAB, providing a convenient, user-modifiable interface, and making it easy to incorporate grating components in MATLAB-based system simulation models. The free demo, tutorial code, and documentation provide a wealth of technical and instructional information and computational capabilities for a range of interesting grating types. You can test GD-Calc's computational performance using the demo examples; run the GD-Calc data validation and plotting functions on your grating structure of interest; and then purchase the P-code calculation engine module to access GD-Calc's full computational capabilities.
