Abstract:A nonlinear hybrid FDTD/FETD technique based on the parametric quadratic programming method is developed for Maxwell’s equations with nonlinear media. The proposed technique allows nonconforming meshes between nonlinear FETD and linear FDTD subdomains. The coarser structured cells of FDTD are used in regular, large and linear media, whereas smaller unstructured elements of FETD based on the parametric quadratic programming method are used to simulate complicated structures with nonlinear media. This hybrid technique is particularly suitable for structures with small nonlinear regions in an otherwise linear medium. Numerical results demonstrate the validity of the proposed method. © 2017, Electromagnetics Academy. All rights reserved.
