Abstract: A unified dispersive media and perfect matching layer (PML) finite-difference time-domain (FDTD) formulation based on the matrix exponential (ME) method is proposed for the simulation of ...
[Fa,Fb,L] = expm_block_tri(A,B,E) computes Fa = e^A, Fb = e^B, and L = D_{exp}(A,B,E), the (1,2) block of exp([A E;O B]), without explicitly computing the exponential of the block triangular matrix, ...
Abstract: Although finite difference time-domain (FDTD) algorithms are potentially applicable to broadband wave propagation and radiation problems, various problems related to the absorbing boundary ...
