Analysis of radiation and scattering problems with the use of hybrid techniques based on the discrete Green's function formulation of the FDTD method
Abstract
In this contribution, simulation scenarios are presented which take advantage of the hybrid techniques based on the discrete Green's function formulation of the finite-difference time-domain (DGF-FDTD) method. DGF-FDTD solutions are compatible with the finite-difference grid and can be applied for perfect hybridization of the FDTD method. The following techniques are considered: (i) DGF-FDTD for antenna simulations, (ii) DGF-based FDTD on disjoint domains, and (iii) hybrid technique combining FDTD and its convolution formulation based on DGF. The presented research employs the new formulation of the FDTD-compatible dyadic DGF derived with the use of scalar DGF and the multidimensional Z-transform. Its software implementation is straightforward because only elementary functions are involved and a single function requires computations in the multiple-precision arithmetic.
