Researchers have developed a physics-constrained neural network (PCNN) designed for the rapid prediction of outputs from rigorous coupled-wave analysis (RCWA). This novel approach enforces energy conservation as a fundamental constraint by projecting outputs onto a Stiefel manifold using differentiable symmetric orthogonalization. The PCNN's effectiveness is demonstrated through its application in the inverse design of a diffractive waveguide combiner intended for augmented reality glasses. AI
