Numerical Stabilization of Recursive T Matrix Method in 2D for TM-z Scattering from Circular Boundaries

The regularization of the well-known recursive T-Matrix method for 2D monochromatic wave scattering problem from multiple circular dielectric cylinder system is elaborated. It is the numerical stabilization of the recursive T-matrix method composed in terms of isolated T-matrices of each scatterer. Numerical results show that it is much safer to proceed with the regularized recurrence operations to get accurate results computer precision can provide by ensuring the reliability of the solution.
