Round-Trip Sensitivity-Bandwidth Optimization and Characterization of High-Frequency PMUTs

Leming He, Ning Lv, Wei-Jiang Xu, Yan Wang, Junyan Ren

Piezoelectric micromachined ultrasonic transducers (PMUTs) are fabricated with Micro-Electro-Mechanical Systems (MEMS) processes. They have advantages such as high uniformity and density, high flexibility in array configuration, and compatibility with integrated circuits. However, PMUTs generally…

New Strategies for CEM Simulation of Microstrip Circuits and Antennas

Raj Mittra, Prashant Chaudhary, Tomislav Marinovic, Abdelkhalek Nasri

This paper describes several novel strategies which help reduce the runtimes and memory requirements when simulating antennas and associated RF circuits in the millimeter-wave region, where the physical size of the radiating module is often large w.r.t. the wavelength. These strategies include the…

Numerical and Experimental Anaysis of Massive MIMO Channel Characteristics in a Rectangular Highway Tunnel at 5.9 GHz

Esteban Egea-Lopez, Jose-Maria Molina-Garcia-Pardo, Martine Lienard, Pierre Laly, Pierre Degauque

To increase channel capacity, MIMO techniques are often used, and now, with the development of the 5G technique, massive transmitting arrays become to be widely implemented. For vehicular communication, the dedicated frequency band is around 5.9 GHz, and, to our knowledge, there are very few…

[Invited] Topological Tamm states based on flat band symmetry inversion

Soufyane Khattou, Amina Rezzouk, Madiha Amrani, Mohamed El Ghafiani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

We study topological Tamm states at the interface between two comb-like photonic or phononic crystals based on a new mechanism of band inversion symmetry due to the existence of flat bands. Several arguments such as the Zak phase or the phase of the reflection coefficients support the topological…

Exceptional points and skin modes in non-Hermitian elastic phononic beams

Yabin Jin, Runcheng Cai, Wenxin Zhong, Timon Rabczuk, Xiaoying Zhuang, Yan Pennec, Bahram Djafari-Rouhani

Exceptional points and skin effect are two hallmarks of non-Hermitian systems combining gain and loss. We demonstrate these phenomena for flexural waves in phononic beams based on applied forces with feedback control. The non-Hermiticity is realized either by means of applying piezoelectric patches…

[Invited] Quasi-Bound States in the Continuum for Acoustic and Elastic Waves

Marc Marti-Sabaté, Junfei Li, Bahram Djafari-Rouhani, Steven Cummer, Daniel Torrent Marti

We study the localization of flexural and acoustic waves in metasurfaces by means of clusters of scatterers. We show that when the scatterers are placed regularly in the perimeter of a circumference these structures form a resonator which quality factor grows up exponentially with the number of…

[Invited] Tunable topological protection from auxeticity and nonlinearity

Maryam Morvaridi, Federico Bosia, Michele Brun, Vinicius Dal Poggetto, Antonio Gliozzi, Marco Miniaci, Nicola Pugno, Giorgio Carta

The dynamic response of an elastic porous material with a periodic distribution of elongated holes is considered. The presence of the cuts makes the effective behavior auxetic and guarantees the presence of multiple Dirac points in the dispersion diagram. By perturbing the microstructure,…
