Abstract

Hybrid potential-field formulation (HPFF) is proposed for broadband electromagnetic solutions of composite problems involving open and closed conducting surfaces. HPFF provides a well-balanced combination of potential and field formulations for electrically large structures with small-scale features, being free of internal-resonance problems and dense-discretization breakdowns.
