Lumerical FDTD is a sophisticated 3D electromagnetic simulation tool specifically tailored for optical device design and analysis. It solves Maxwell's equations directly in the time domain using the Yee algorithm, which discretizes both space and time. This approach allows researchers to study how electromagnetic waves—particularly light in the visible and near-infrared spectrum—propagate, scatter, and interact with complex dielectric structures.
