This paper investigates the performance of three hierarchical matrix (H-matrix) formats for modeling electromagnetic devices using the Electric Field Integral Equation (EFIE) and the Augmented EFIE (A-EFIE) formulation. These methods are applied to a benchmark problem, the single-ended microstrip transmission line, to evaluate their efficiency in terms of memory usage and accuracy.

Abstract
This paper investigates the performance of three hierarchical matrix (H-matrix) formats for modeling electromagnetic devices using the Electric Field Integral Equation (EFIE) and the Augmented EFIE (A-EFIE) formulation. These methods are applied to a benchmark problem, the single-ended microstrip transmission line, to evaluate their efficiency in terms of memory usage and accuracy.
