Abstract:

Models for non-linear dielectrics and magnetic ferrites are developed and coded into the particle-in-cell code ICEPIC. The non-linear dielectric model includes a relaxation term to account for the physical response time of the material, which may be longer than an FDTD time step. The ferrite model accounts for the non-linearity of the Landau-Lifshitz-Gibert equation, and the magnetization update is derived from the solution of the equation on a time step. Initial testing of the models is encouraging, and work is underway on further improvement and refinement.
