Design of novel radiating elements for SATCOM phased arrays in Ku-Band

Baptiste Fernand Hornecker

The present thesis deals with the design of a planar antenna array for the communication between a civil aircraft (Dassault's Falcon) and an Inmarsat satellite. The final goal is to provide high speed Internet access in X/Ku-Band (8-12GHz / 12-18GHz), and ...

Electromagnetic inspired acoustic leaky-wave antenna

Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

In this article we make an analogy between Electromagnetic and Acoustic transmission-line modelling. Then we use this to introduce acoustic transmission-line metamaterials and finally we introduce the acoustic leaky-wave antenna on the basis of previous st ...

Tx-Rx Lens-Based Satellite-on-the-Move Ka-Band Antenna

Juan Ramon Mosig, Joana Rita Alves dos Santos Silva

A simple low-cost mobile ground terminal antenna for Ka-band satellite communications is presented. The antenna is composed of a shaped dielectric lens which tilts and rotates in front of a feed to direct the beam. The wideband feed system is composed of a ...

A Novel Bridge Section Model Endowed with Actively Controlled Flap Arrays Mitigating Wind Impact

Alcherio Martinoli, Klara Maria Boberg

In this work, we present the SmartBridge, a novel bridge section model equipped with actively controlled arrays of flaps aiming at mitigating wind-induced vibrations of long-span bridges. The active model, as well as its support structure, is described in ...

Multi-band reflectarray antennas in Ku and THz frequency bands

Hamed Hasani

Printed reflectarrays are low-cost, low-profile high gain antennas demonstrating distinctive advantages over conventional parabolic reflectors and phased-arrays. The flat, low weight reflecting surface of a reflectarray makes it an attractive alternative w ...

A sound diffusion system for directional sound enhancement

Hervé Lissek, Xavier Falourd, Patrick Marmaroli, Alain Dufaux, Baptiste Crettaz

A loudspeaker array is described including several circular sound emitters that are bunked. One circular sound emitter can be either a circular array of loudspeakers (kind 1) or a toroidal loudspeaker (kind 2). The loudspeaker array can be composed of circ ...
