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…

The Upper Bound on Antenna Gain and Its Feasibility as a Sum of Characteristic Gains
Miloslav Capek, Lukas Jelinek
The upper bound on antenna gain is expressed as a sum of lossy characteristic modes, specifically, as a sum of characteristic far fields squared. The procedure combines the favorab…
