Near-field measurement and far-field characterization of a J-band antenna based on an electro-optic sensing

Shintaro Hisatake, Yusuke Tanaka, Cybelle Belem-Gonçalves, Cyril Luxey, Frédéric Gianesello, Guillaume Ducournau, Akihiko Hirata

In this paper, we present a near-field pattern measurement based on an electro-optic sensing at 300 GHz band. The measurement system is based on a self-heterodyne technique and non-polarimetric frequency down-conversion technique. The far-field radiation pattern of a horn antenna calculated from…

Application of the GPR and ERT methods for non-invasive examination of a flood dike

Tomislaw Golebiowski, Bogdan Piwakowski, Michal Cwiklik

As part of the NAWA-EMMAT project, geophysical surveys were carried out on selected sites in Poland, i.e. on the flood dike and in the surrounding of the concrete water dam. The goal of the surveys was the non-invasive detection of loose zones in the flood dike and fractured zones located in the…

On the teaching mode in online course of MEMS fundamental theory

Jinying Zhang, Wei-Jiang Xu, Xianmei Wu, Zhuo Li, Xin Wang, Suhui Yang

Massive offline courses have been transferred to online in higher education reform all over the world. This paper presents a teaching mode integrated with finite element numerical simulation in the fundamental theory study in MEMS (Micro-Electro-Mechanical Systems) online course for the graduate…

Effects of the electrical limit conditions on the electromechanical behavior of piezoelectric transducer arrays

Abdelmajid Bybi, Adil Ammar, Mohammed Garoum, Sébastien Grondel, Ahmed Mzerd, Anne-Christine Hladky

Crosstalk is an undesirable phenomenon having a negative impact on the electroacoustic performance of ultrasonic transducer arrays, utilized in medical imaging and NDT applications. Indeed, when one element of a transducer array is excited, it generates parasitic voltages and/or displacement fields…
