Reconfigurable Pixel-Layer Isolator for Frequency-Tunable On-Frequency Repeaters

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 ...

Dual-Polarized Partially Reflective Surface Antenna With MEMS-Based Beamwidth Reconfiguration

Julien Perruisseau-Carrier, Tomislav Debogovic

A partially reflective surface (PRS) antenna design enabling 1-bit dynamic beamwidth control is presented. The antenna operates at X-band and is based on microelectromechanical systems (MEMS) technology. The reconfigurable PRS unit cell monolithically inte ...

Monolithic Metal-Coated Plastic Components for mm-Wave Applications

Jean-Philippe Ansermet, Arndt Christian von Bieren, Emile Jacques de Rijk, Alessandro Macor

A stereolithography-based manufacturing process for monolithic high aspect ratio components for mm-wave and sub-mm-wave applications is demonstrated. A 25mm long straight waveguide and a diagonal horn antenna, both for the WR-3.4 band (220–330 GHz), are ma ...

Knowledge Specialization in Ph.D. Student Groups

Fabiana Visentin, Annamaria Conti

Researchers have argued that specialization within groups yields productivity gains. We evaluate this statement with a focus on groups of Ph.D. students. Using an established technique in computer science called Latent Dirichlet Allocation, we construct a ...

Design, Realization, and Experimental Test of a Coaxial Exponential Transmission Line Adaptor for a Half-Impulse Radiating Antenna

Nicolas Mora Parra

This paper describes the simulation, design, realization, and experimental test of a tapered transmission line (TL) for adapting a broad-band impulse generator to a radiating antenna, for a frequency range of 50 MHz-1 GHz. Two different taper geometries ar ...

On the Electromagnetic Susceptibility of Hot Wire-Based Electroexplosive Devices to RF Sources

Nicolas Mora Parra

We present an analysis of the thermal response of a hot-wire electroexplosive device (EED) excited with different transient signals. First-order and second-order analytical models to calculate the thermal response of an EED are assessed taking as reference ...

Closed-form expressions for modeling diffraction at printed dipole-based FSS

Juan Ramon Mosig, Maria Garcia Vigueras

This paper presents analytical expressions to model the diffraction of plane-waves at planar 2-D distributions of printed dipoles. In contrast to other available analytical or quasi-analytical models, this approach rigorously captures the main underlying p ...

Soft and Flexible Antennas on Permittivity Adjustable PDMS Substrates

Anja Skrivervik, Jean-François Zürcher, Jovanche Trajkovikj

This work presents novel techniques for producing substrates for flexible antennas. The technique we propose is based on the use of an already existing and widely used substrate material Polydimethylsiloxane (PDMS), where the dielectric properties of the s ...
