Negative refraction of elastic waves in 2D phononic crystals : contribution of resonant transmissions to the construction of the image of a point source

Anne-Christine Hladky, Charles Croënne, Bertrand Dubus, Jerome O. Vasseur, L. Haumesser, D. Manga, B. Morvan

Negative refraction properties of a two-dimensional phononic crystal (PC), made of a triangular lattice of steel rods embedded in epoxy are investigated both experimentally and numerically. First, experiments have been carried out on a prism shaped PC immersed in water. Then, for focusing purposes…

Demonstration of low leakage current and high polarization in ultrathin AlN/GaN high electron mobility transistors grown on silicon substrate

F Medjdoub, Malek Zegaoui, N. Rolland, Paul-Alain Rolland

High quality AlN/GaN heterostructures grown on silicon substrate are demonstrated. It is found that high carrier concentration can be achieved whereas circular diodes showed a low leakage current up to 200 V reverse bias. 200 nm gate length AlN/GaN transistors exhibited a drain current density of 1…

A LiNbO3 ultrasonic phased array transducer of more than 100 MHz

Wei-Jiang Xu, X.M. Ji, Jin-Ying Zhang, Julien Carlier, Bertrand Nongaillard, S. Queste, Y.P. Huang, Bogdan Piwakowski

High-frequency ultrasonic transducer arrays are essential for high resolution imaging in clinical analysis and Non-Destructive Evaluation (NDE). However, the structure design and fabrication of the kerfed ultrasonic array is quite challenging when very high frequency (≥ 100 MHz) is required.…
