Finite-difference time-domain method

Numerical Algorithm

The finite-difference time-domain method, known as FDTD or Yee's method, is a numerical analysis technique for modeling electromagnetic fields in computational electrodynamics. It marches Maxwell's curl equations forward in time on a grid in which the electric and magnetic field components are staggered in both space and time, and it uses centered finite differences to update each component from its neighbors. Kane S. Yee introduced this staggered scheme in his 1966 paper, and Allen Taflove coined the name finite-difference time-domain in 1980. Because the grid must resolve the smallest wavelength and the smallest geometric feature, large models take long to solve, but the method scales well on parallel processors and graphics hardware. It is used for radar signatures, antennas, wireless devices, photonic crystals, nanoplasmonics and biomedical imaging.
