Fundamental bounds on transmission through periodically perforated metal screens with experimental validation
Andrei Ludvig-Osipov, Johan Lundgren, Casimir Ehrenborg +5
This paper presents a study of transmission through arrays of periodic sub-wavelength apertures. Fundamental limitations for this phenomenon are formulated as a sum rule, relating…
Optimal Planar Electric Dipole Antenna
Miloslav Capek, Lukas Jelinek, Kurt Schab +4
Considerable time is often spent optimizing antennas to meet specific design metrics. Rarely, however, are the resulting antenna designs compared to rigorous physical bounds on tho…
Energy Stored by Radiating Systems
Kurt Schab, Lukas Jelinek, Miloslav Capek +4
Though commonly used to calculate Q-factor and fractional bandwidth, the energy stored by radiating systems (antennas) is a subtle and challenging concept that has perplexed resear…
Fundamental bounds on MIMO antennas
Casimir Ehrenborg, Mats Gustafsson
Antenna current optimization is often used to analyze the optimal performance of antennas. Antenna performance can be quantified in e.g., minimum Q-factor and efficiency. The perfo…
