In this paper, FDTD algorithm has been derived for magnetized plasma which resembles both anisotropic and dispersive medium. A thin slab of perpendicularly magnetized nickel has been illuminated by the terahertz light wave. The transient solution of problem has been done by an x-polarized incident wave, which results in production of y-component of electric field. Simulation results show the Kerr rotation angles of over 0.15 degree for 100 nm thicknesses of Nickel slab. CP - IRAN IN - LG - eng PB - opsi PG - 1277 PT - Research YR - 2015
