The numerical implementation of FDTD involves discretizing the computational domain into a grid of cells. Each cell is assigned material properties, such as permittivity and permeability. The FDTD algorithm then updates the electric and magnetic fields at each cell using the finite-difference equations. The algorithm consists of two main steps:
