Iterative multiregion technique for large-scale electromagnetic scattering problems: Two-dimensional case

[1] One of the methods to solve large electromagnetic problems is to divide the computational domain into smaller subregions and solve each subregion separately. Then the subregion solutions are combined to obtain a solution for the complete domain. In this paper, an iterative approach using the finite difference frequency domain method is presented to solve the problems that can be divided into separated subregions.
