Characteristic Mode Analysis of Acoustic Scatterers
Lukas Jelinek, Kurt Schab, Viktor Hruska +2
The explicit connection between the transition matrix and boundary element method integral operators is formulated. This enables the calculation of characteristic modes via eigenva…

Characteristic Modes of Frequency-Selective Surfaces and Metasurfaces from S-parameter Data
Kurt Schab, Frederick Chen, Lukas Jelinek +3
Characteristic modes of arbitrary two-dimensional periodic systems are analyzed using scattering parameter data. This approach bypasses the need for periodic integral equations and…
