Ultra-Low Power Short-Range 60-GHz FMCW Radar Front-End

Sammy Cerida Rengifo

The millimeter wave (mmWave) frequency band is becoming very interesting over the past years because it provides the opportunity to operate using large bandwidths which are not available at lower frequencies. This enables new communication standards suppor ...

Directional Cross-Correlation for Improved Aberration Phase Estimation in Pulse-Echo Speed-of-Sound Imaging

Jean-Philippe Thiran, Samuel Denys Beuret, Simon Canales

There has been a recent surge in methods targeting the recovery of a speed-of-sound map from pulse-echo ultrasound measurements. We focused in this work on a particular technique and identified a drawback shared by similar methods - namely the necessity of ...

Four-Port Broadband Orthomode Transducer Enabling Arbitrary Interelement Spacing

Juan Ramon Mosig, Anja Skrivervik, Emile Jacques de Rijk, Tomislav Debogovic, Maria Garcia Vigueras, Santiago Capdevila Cascante, Esteban Menargues Gomez

This paper reports a novel methodology to design broadband orthomode transducers with two arbitrarily spaced ports carrying orthogonal linear polarizations. The component is based on a combination of two Boifot junctions through a series of power dividers ...

Design and Implementation of a Neural Network Aided Self Interference Cancellation Scheme for Full-Duplex Radios

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Yann Kurzo

In-band full-duplex systems are able to transmit and receive information simultaneously on the same frequency band. Due to the strong self-interference caused by the transmitter to its own receiver, the use of non-linear digital self interference cancellat ...

Modulated scattering technique in the terahertz domain enabled by current actuated vanadium dioxide switches

Juan Ramon Mosig, Mihai Adrian Ionescu, Anja Skrivervik, Michele Tamagnone, Wolfgang Amadeus Vitale, Santiago Capdevila Cascante

The modulated scattering technique is based on the use of reconfigurable electromagnetic scatterers, structures able to scatter and modulate an impinging electromagnetic field in function of a control signal. The modulated scattering technique is used in a ...
