Abstract

Grid-compatible discrete Green´s functions (DGFs) in cylindrical grid, derived from the first principles of the FDTD-discretized Maxwell´s equations, enable the hybridization between differential and integral equation based numerical methods. The DGF replicates the FDTD solutions, as opposed to an outright discretization of the continuous Green´s function (CGF). We focus on the two dimensional case in cylindrical grid that is attractive since it is inherently axially symmetric, such that it fits the description of a point source.
