Explicit formulation of second and third order optical nonlinearity in the FDTD framework [PDF]
Computer Physics Communications, 222, 70-83 (2018), 2016 The finite-difference time-domain (FDTD) method is a flexible and powerful technique for rigorously solving Maxwell's equations. However, three-dimensional optical nonlinearity in current commercial and research FDTD softwares requires solving iteratively an implicit form of Maxwell's equations over the entire numerical space and at each time step ...

A rotated subgrid for 3D FDTD [PDF]
2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2015 In most published work on subgrids for the FDTD method, Cartesian subgrids are proposed which are in the same orientation as the main grid. However there is considerable benefit to allowing for the subgrid to be rotated. In this work, a novel method for introducing a rotated subgrid into the mesh is presented and some preliminary results are given.
