Directivity Estimates and Tolerance Tradeoffs in the Presence of Random Perturbations
Kurt Schab, Lukas Jelinek, Miloslav Capek +1
The practicality of realizing high-directivity sources is studied using a generalized sensitivity metrics. These measures are based on the error model adopted in previous studies o…
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…
Theory and Computation of Substructure Characteristic Modes
Mats Gustafsson, Lukas Jelinek, Miloslav Capek +2
The problem of substructure characteristic modes is developed using a scattering matrix-based formulation, generalizing subregion characteristic mode decomposition to arbitrary com…
Characteristic Modes of Nonreciprocal Structures
Niklas Wingren, Daniel Sjöberg, Mats Gustafsson +4
The scattering formulation of characteristic mode decomposition is utilized to extend modal analysis to lossless scatterers breaking time-reversal symmetry. This enables characteri…
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…
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…
