Simulating Maxwell's Equations with Automatic Differentiation

We wrote core Maxwell's Equations solvers using the HIPS autograd package, and defined custom primitives for performing backpropagation through electromagnetic simulations.

This allows one to effortlessly perform gradient-based optimization of optical devices, as well as plug electromagnetic simulations into a machine learning model.
