Metagrating Topology Optimization
Jonathan Fan, Stanford University
Basic topology optimization codebase for simple periodic metasurface deflectors or metagratings. This package utilizes adjoint-based gradient descent in order to generate devices with freeform geometries. Such devices are physically complex and demonstrate ultra-high efficiencies.
