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…
Joint Signal and Topology Optimization for Maximum Instantaneous Field Intensity
Jakub Liska, Lukas Jelinek, Miloslav Capek
This paper introduces a computational approach to identify performance constraints in the time-domain, offering a way to design systems in pulse operation. This work presents a com…
Optimization of Embedded Element Patterns of Reactively Loaded Antenna Arrays
Albert Salmi, Miloslav Capek, Lukas Jelinek +2
This paper introduces a framework for synthesizing reactively loaded antennas and antenna arrays. The framework comprises two main components: computing the fundamental bound using…
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…
Generalized Friis Transmission Formula Using Active Antenna Available Power and Unnamed Power Gain
Karl F. Warnick, Frederic Broyde, Lukas Jelinek +2
We use the concept of active antenna available power to derive a generalization of the Friis transmission formula for multiport antenna systems. With beamformer weights chosen such…
