Published Updated Story ID: mp-2026-08-07-018
Summary
A differentiable coupled-wave method directly builds scattering matrices for anisotropic structures.
The framework avoids eigendecomposition of large non-Hermitian matrices, supports GPU acceleration and automatic differentiation, and reports a 25-fold speedup at comparable accuracy for forward analysis and inverse design.
