The FDTD method was first introduced by Kane Yee in 1966 and has since become a popular choice for solving Maxwell's equations in various fields. The method discretizes both space and time, dividing the computational domain into a grid of cells and updating the electric and magnetic fields at each cell using finite-difference equations. The FDTD method is widely used for simulating and analyzing various optical systems, including photonic crystals, optical fibers, and solar cells.
