Iterative Calculation of Characteristic Modes Using Arbitrary Full-wave Solvers
Johan Lundgren, Kurt Schab, Miloslav Capek +2
An iterative algorithm is adopted to construct approximate representations of matrices describing the scattering properties of arbitrary objects. The method is based on the implici…
