Abstract | Two Krylov subspace-based methods are used to solve the sparse matrix generated by the finite difference formulation. The use of the bi-Lanczos algorithm allows this method to be computationally competitive with other approximate methods while the use of the finite difference formulation makes this method versatile enough to handle complicated waveguide structures. The BiCG-based algorithm reduces the storage requirements to O(N) and thus can handle problems with several hundred thousand unknowns. The speed of this algorithm is further enhanced by using a non-uniform grid in the solution space outside the dielectric waveguide. By using a non-uniform grid, the size of the artificial boundary is greatly increased which limits the error in the results. |
