High Contrast Grating Solver Package
A high contrast grating solver (HCG Solver) is developed to solve the reflection and transmission coefficient of a plane wave incident onto a single layer of high contrast grating (HCG). It uses plane waves and waveguide array modes as the eigen modes to expand the electromagnetic field outside and inside the HCG respectively. By matching the boundary conditions at the HCG input plane and output plane, the electromagnetic property of HCG can be solved.
The HCG Solver is written using MatlabŪ, from The MathWorks. The program is developed by Weijian Yang, and optimized by Vincent Wang and Weijian Yang, in Prof. Connie Chang-Hasnain's Group in University of California, Berkeley. Any feedback should be delivered to the form on our website.
MATLAB R2010b or newer. Tested on OSX and Windows.
