Selective dynamic band gap tuning in metamaterials using graded photoresponsive resonator arrays

V.F. Dal Poggetto, D. Urban, F. Nistri, P.H. Beoletto, E. Descrovi, M. Miniaci, N. Pugno, F. Bosia, A. Gliozzi

The introduction of metamaterials has provided new possibilities to manipulate the propagation of waves in different fields of physics, ranging from electromagnetism to acoustics. However, despite the variety of configurations proposed so far, most solutions lack dynamic tunability, i.e. their…

Characterization of Schottky Diodes at Wafer Level for Frequency Multipliers Applications Based on RF Coplanar Measurements

Hugo Bouillaud, Yannick Roelens, Etienne Okada, Jeanne Treuttel, Priyanka Mondal, Pierre Gellie, Mohammed Zaknoune, Guillaume Ducournau

While Schottky diode for THz generation have been extensively studied over last decades, technological developments are still required to reach the physical limits of these devices, such as breakdown voltage or sub-μm devices, but also efficient thermal management in particular before their…

A Convolution-Assisted Vision Transformer for the Classification of Pancreatic Ductal Adenocarcinoma

Michael Selasi Dzamesi, Feryal Windal, Karim Hammoudi, Emmanuelle Leteurte, Halim Benhabiles

Many works that require the classification of whole slide images (WSIs) primarily involve classifying patches extracted from the WSIs. The classes from the patches are extrapolated as the class of the WSI. Pathologists, however, consider the surrounding region of a patch before classifying it. We…

Miniaturized 6 MHz phased-array ultrasound probe based on lead-free doped BaTiO3 piezoceramics

Claire Bantignies, Loïck Bonnet, Rémi Rouffaud, Monique Pouille, Ana Borta-Boyon, Franck Levassort

For many years, piezoelectric PZT-based materials for medical imaging have an exemption in the RoHS Directive that may not be reconducted in the future. Commercially and production-compatible products for substitution are still rare on the market. BaTiO3 is a well-known lead-free composition that…

Optimization of the melt and quench behavior of phase-change RF switch to improve power handling

Corentin Mercier, Bruno Reig, Stéphane Monfray, Emmanuel Dubois, Alain Fleury, Frederic Gianesello, Vincent Puyal, Ismaël Charlet, J. Lugo-Alvarez, Clémence Hellion, Marjolaine Allain, Joey Denizart, J.F. Robillard

This paper presents two methods to improve the reliability and the melting/quench behavior of phase change materials (PCM) used in radiofrequency (RF) switches. Results show benefits of the addition of an aluminum nitride heat spreading layer and the reduction of the distance between the substrate…

A Versatile Balun Based on a Power Divider Topology

Lucie Jeannin, Larbi Boukhezar, Olivier Occello, Loïc Vincent, Guillaume Ducournau, Marc Le Roy, André Pérennec, Philippe Ferrari

This paper presents an original balun concept based on a power divider topology. The proposed concept simplifies the design compared to a Marchand balun by eliminating the interconnection problem between the two couplers forming the Marchand balun. Furthermore, the proposed concept is highly…
