A multi-region (MR-) finite-difference time-domain (FDTD) scheme for solving two-dimensional sparsely-populated problems based on domain-optimal Green's functions is proposed. The scheme uses a discrete Green's function (DGF) on the FDTD lattice to truncate the local sub-regions and thus reduces reflection error on the local boundary. A continuous Green's function (CGF) is implemented to pass the...
The finite difference delay modeling method is applied to the solution of two-dimensional electromagnetic scattering problems. The spatial discretization is carried out by the locally corrected Nyström method with arbitrary, analytically-described geometry models to achieve a method that exhibits higher-order convergence in both space and time. The efficacy and accuracy of the method are demonstrated...
In this work, we propose an unconditionally stable TDIE method using the locally corrected Nystrδm (LCN) method for spatial discretization and finite difference delay modeling (FDDM) for temporal discretization. The use of a Nystrδm method reduces the time required to create the discrete convolution kernel, and simplifies the use of curved geometry models and fast methods. Finally, by applying FDDM...
