Maximum Gain, Effective Area, and Directivity
Mats Gustafsson, Miloslav Capek
Fundamental bounds on antenna gain are found via convex optimization of the current density in a prescribed region. Various constraints are considered, including self-resonance and…
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…
Stored energies for electric and magnetic current densities
B. L. G. Jonsson, Mats Gustafsson
Electric and magnetic current densities are an essential part of electromagnetic theory. The goal of the present paper is to define and investigate stored energies that are valid f…
On the natural modes of helical structures
Sven Nordebo, Mats Gustafsson, Gerhard Kristensson +3
Natural modes of helical structures are treated by using the periodic dyadic Green's functions in cylindrical coordinates. The formulation leads to an infinite system of one-dimens…
