Life sciences have a constantly growing need for novel methodological approaches suitable to investigate the intracellular environment with increased temporal and spatial resolutions. Recently, optical near-field probes, such as laser-irradiated pointed me ...
This dissertation aims to explore the design trade-offs and technological limitations of planar antenna elements and arrays for Ka-band space applications. The motivation for this research stems from the growing importance of wideband millimetre wave radio ...
In an article (Zurcher, Microwave Opt Technol Lett 55 (2013), 516-521) published in 2013, a new antenna called tripod omnidirectional low profile Antenna has been presented. It is vertically polarized and has a radiation pattern similar to the classical mo ...
Small antennas, or more specifically, electrically small antennas, are passive radiating elements whose size is much smaller than the operating wavelength. The current wireless application systems usually have size constraints that, for the most common ope ...
The maximum gain in on-frequency repeaters is limited by the isolation level between their two antennas due to close-loop stability conditions. In this letter, a novel pixel-layer isolator for tunable on-frequency repeaters is presented. The scattered fiel ...

This communication presents a reconfigurable antenna capable of independently reconfiguring the operating frequency, radiation pattern and polarization. A switched grid of small metallic patches, known as pixel surface, is used as a parasitic layer to prov ...
The analysis of a radio-frequency (RF) planar antenna is presented for applications in plasma processing. The antenna is a network of elementary meshes composed of inductive and capacitive elements which exhibits a set of resonant modes. The high currents ...
We demonstrate a high-throughput biosensing device that utilizes microfluidics based plasmonic microarrays incorporated with dual-color on-chip imaging toward real-time and label-free monitoring of biomolecular interactions over a wide field-of-view of > 2 ...
Bloch surface waves (BSWs) are surface electromagnetic waves excited at the interface between a truncated periodic dielectric multilayer and a surrounding medium. This particular solution to the Maxwell equations in stratified media has been known since th ...
Abstract|We propose different concepts of mechanically recon¯gurable true-time-delay phaseshifters using micro-actuators at millimeter-waves (MMW). The mechanical reconfiguration allows to achieve phase shift reconfiguration with very low losses. One of th ...
