Design of zero bias power detectors towards power consumption optimization in 5G devices

Issa Alaji, Walid Aouimeur, Haitham Ghanem, Etienne Okada, Sylvie Lepilliet, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière

This paper presents the design and characterization of zero bias power detectors, based on MOSFET transistors, integrated in SiGe 55-nm BiCMOS technology from ST-Microelectronics. The working frequency bands of the circuits are located in the range (38–55) GHz, dedicated to optimize the power…

Evaluation of an antenna selection strategy for reduced massive MIMO complexity

Frédéric Challita, M. Lienard, Davy Gaillot, Jose-Maria Molina-Garcia-Pardo

Massive Multiple-Input Multiple-Output (MIMO) is emerging as one promising technology for the fifth generation (5G), but the hardware and software complexity arising from the sheer number of transmitting elements is a bottleneck. Antenna selection strategies have been reported as an appealing…

Coplanar waveguides on BCB measured up to 760 GHz

Nicolas Zerounian, Walid Aouimeur, Anne-Sophie Grimault-Jacquin, Guillaume Ducournau, Christophe Gaquière, Frédéric Aniel

The integrated THz pattern over any MMIC appears to be a good opportunity to enclose calibration kit suitable for accurate measurements. An original technology based on polymer has been developed. Sub-millimeter single-mode conductor-backed coplanar waveguides using benzocyclobutene polymer and…

Broadband sub-diffraction and ultra-high energy density focusing of elastic waves in planar gradient-index lenses

Jinfeng Zhao, Xiaodong Cui, Bernard Bonello, Bahram Djafari-Rouhani, Weitao Yuan, Yongdong P Pan, Jie Ren, Xiaoqing Zhang, Zheng Zhong

We demonstrate experimentally and theoretically the broadband sub-diffraction and ultra-high energy density focusing of elastic wave inside planar gradient-index (GRIN) plate lenses based on thickness variation. The full width at half maximum is ~0.40 times the minimum wavelength inside the lens λ0…

Concept of vertical liquid metal actuated cyclo‐olefin‐polymer based embedded 360° steerable Yagi‐Uda antenna

Denis Le Goff, Yves Quéré, Azar Maalouf, Eric Rius, Philippe Coquet, Edwin Hang Tong Teo

The concept of a reconfigurable 5GHz microfluidically actuated antenna with beam forming, steering and hoping in a 360° angular range, is presented in this paper. Its architecture is that of a Yagi-Uda array. Its actuation relies on the electrically controlled vertical displacement of liquid metal…

Abnormal topological refraction into free medium at sub-wavelength scale in valley phononic crystal plates

Linyun Yang, Kaiping Yu, Bernard Bonello, Bahram Djafari-Rouhani, Wei Wang, Ying Wu

In this work we propose a topological valley phononic crystal plate and we extensively investigate the refraction of valley modes into the surrounding homogeneous medium. This phononic crystal includes two sublattices of resonators (A and B) modeled by mass-spring systems. We show that two edge…

Entropy production and Onsager reciprocal relations describing the relaxation to equilibrium in stochastic thermodynamics

Stefano Giordano

We study the relation between stochastic thermodynamics and non-equilibrium thermodynamics by evaluating the entropy production and the relation between fluxes and forces in a harmonic system with N particles in contact with N different reservoirs. We suppose that the system is in a non-equilibrium…

Band gap enhancement in periodic frames using hierarchical structures

Vinícius Dal Poggetto, Federico Bosia, M. Miniaci, Nicola Pugno

The quest for novel designs for lightweight phononic crystals and elastic metamaterials with wide low-frequency band gaps has proven to be a significant challenge in recent years. In this context, lattice-type materials represent a promising solution, providing both lightweight properties and…

Facile synthesis of fluorine-free, hydrophobic, and highly transparent coatings for self-cleaning applications

Abderrahmane Hamdi, Julie Chalon, Pascal Laurent, Benoit Dodin, El Hadj Dogheche, Philippe Champagne

Non-fluorinated coatings have recently emerged as a new approach to avoid contamination on transparent surfaces. This research work concerns the synthesis of highly transparent, hydrophobic, durable, and self-cleaning coatings as an alternative to fluorine-based coatings used on glass. The…
