Characteristic mode analysis of acoustic scatterers

Jelinek, Lukas ; Schab, Kurt LU ; Hruska, Viktor ; Capek, Miloslav LU and Gustafsson, Mats LU orcid (2025) In Journal of Sound and Vibration 618.
Abstract

The explicit connection between the transition matrix and boundary element method integral operators is formulated. This enables the calculation of characteristic modes via eigenvalue problems involving either set of operators, leading to convenient orthogonality properties facilitating scattering analysis, solution of inverse problems, and the design of excitation fields. MATLAB implementation of the findings is also provided.
