Abstract:A finite-element time-domain method is developed for Maxwell's equations with nonlinear media. Compared with conventional nonlinear numerical methods, the proposed scheme is not based on iterations, but using the quadratic programming method. The nonlinear constitutive relations are treated as a series of linear complementary problems, thus, this scheme presents very good convergence behavior in computation. Numerical results demonstrate the validity of the proposed method. (c) 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1640-1645, 2015
