Generation of acoustic helical wavefronts using metasurfaces
Juan Ramon Mosig, Hervé Lissek, Seyyed Hussein Seyyed Esfahlani
It has been shown that acoustic waves with helical wavefronts can carry angular momentum, which can be transmitted towards a propagating medium. Such a wave field can be achieved by using a planar array of electroacoustic transducers, forming a given spati ...
2017Design and Measurement of a Differential Printed Antenna for a Wireless Sensor Network Node
Anja Skrivervik, Nuno Miguel Faria Pires
This letter presents the design and measurement of an antenna integrated into an agricultural sensor network node operating on the 2.4-GHz ISM band using the ZigBee protocol stack. The novel structure, coined bowtie-shaped folded dipole (BSFD), has a diffe ...

Jürgen Brugger, Duncan Thomas Lindsay Alexander, Pamina Winkler, Valentin Flauraud, Raju Regmi
Optical nanoantennas have a great potential for enhancing light-matter interactions at the nanometer scale, yet fabrication accuracy and lack of scalability currently limit ultimate antenna performance and applications. In most designs, the region of maxim ...
American Chemical Society2017Carrier Tracking using Extended Kalman Filters for GNSS Synthetic Aperture Processing with a Rotating Antenna
Pierre-André Farine, Joaquin Cabeza de Pablo, Cyril Botteron, Miguel Angel Ribot Sanfelix
A single GNSS antenna moving along a known trajectory can be used to synthesize a virtual array in order to apply spatial diversity techniques, e.g. beamforming. With these techniques, referred as synthetic aperture (SA) techniques, the receiver can mitiga ...
2017Antennas for low-cost Ka-band ground terminal devices
Joana Rita Alves dos Santos Silva
The ever-growing demand for high-speed data links together with the increasing congestion in the traditional microwave spectrum are pushing for the exploitation of higher microwave and millimeter-wave (mm-wave) frequencies, including the so-called Ka band. ...
EPFL2017Experimental verification of optimal frequency range for microwave head imaging
Jean-Philippe Thiran, Juan Ramon Mosig, Michael Mattes, Mina Bjelogrlic, Benjamin Fuchs
This work presents the experimental verification of the power transmission of a radiating field into the human head for Microwave Imaging (MWI) applications. We aim at finding the range of frequencies that optimize the power scattered by any anomalies from ...
2017Design of Compact Air-Vias-Perforated SIW Horn Antenna With Partially Detached Broad Walls
A novel substrate-integrated waveguide (SIW) horn antenna with partially detached broad walls is designed and analyzed. The conventional SIW horn antenna suffers from narrow-operating bandwidth, which mainly results from the mismatch at the horn aperture b ...
Ieee-Inst Electrical Electronics Engineers Inc2016Dielectric Resonator Reflectarray as High-Efficiency Nonuniform Terahertz Metasurface
Advances in terahertz technology rely on the combination of novel materials and designs. As new devices are demonstrated to address the terahertz gap, the ability to perform high-efficiency beam control will be integral to making terahertz radiation a prac ...
Amer Chemical Soc2016Design of novel radiating elements for SATCOM phased arrays in Ku-Band
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 ...
