Low-Profile Circularly Polarized Array With Gain Enhancement and RCS Reduction Using Polarization Conversion EBG Structures KU Leuven
Time-Domain Electromagnetic-Field Transmission Between Small-Loop Antennas on a Half-Space With Conductive and Dielectric Properties KU Leuven
A dual-band dual-polarized wearable array is proposed, based on a miniaturized innovating button radiator topology. The diameter of the rigid button is only 19.5 mm (0.29 λ at 4.5 GHz), which optimizes the users' comfort, and makes it the smallest up to date in literature. The operational bands are 4.50-4.61 GHz and 5.04-5.50 GHz. The antenna thus covers the 4.5-4.6 unlicensed future 5th generation (5G) communication band for the internet of ...

Appropriate Nonlocal Hydrodynamic Models for the Characterization of Deep‐Nanometer Scale Plasmonic Scatterers KU Leuven
The interaction between light and plasmonic systems with deep‐nanometer characteristics, which is essentially governed by quantum mechanical effects, has been extensively studied by the nonlocal hydrodynamic approach. Several hydrodynamic models, supplemented by additional boundary conditions, have been introduced in order to describe the collective motion of the free electron gas in metals. Four hydrodynamic models, namely the hard wall ...
