A Role of Symmetries in Evaluation of Fundamental Bounds
Miloslav Capek, Lukas Jelinek, Michal Masek
A problem of the erroneous duality gap caused by the presence of symmetries is solved in this paper utilizing point group theory. The optimization problems are first divided into t…
Excitation of Orthogonal Radiation States
Michal Masek, Lukas Jelinek, Miloslav Capek
A technique of designing antenna excitation realizing orthogonal states is presented. It is shown that a symmetric antenna geometry is required in order to achieve orthogonality wi…
Finding Optimal Total Active Reflection Coefficient and Realized Gain for Multi-port Lossy Antennas
Miloslav Capek, Lukas Jelinek, Michal Masek
A numerically effective description of the total active reflection coefficient and realized gain are studied for multi-port antennas. Material losses are fully considered. The desc…
Modal Tracking Based on Group Theory
Michal Masek, Miloslav Capek, Lukas Jelinek +1
Issues in modal tracking in the presence of crossings and crossing avoidances between eigenvalue traces are solved via the theory of point groups. The von Neumann-Wigner theorem is…
Analytical Representation of Characteristic Modes Decomposition
Miloslav Capek, Pavel Hazdra, Michal Masek +1
Aspects of the theory of characteristic modes, based on their variational formulation, are presented and an explicit form of a related functional, involving only currents in a spat…
