Exceptional points for crack detection in non-Hermitian beams

Yabin Jin, Wenjun Li, Bahram Djafari-Rouhani, Yan Li, Yanxun Xiang

We study exceptional points (EPs) in parity-time (PT) symmetric non-Hermitian beams and explore their applications in crack detection. The EPs are formed by coupling different beam modes under feedback-controlled forces. The variations of the required non-Hermitian coefficient for the achievement…

Engineering and optimization of the SPR device ZnO/Ag/WO3/Ni/2D-Nanomaterials highly sensitive for biomedical processing and detection

Mohamed El Barghouti, Fatima Houari, Abdellatif Akjouj, Abdellah Mir

In this paper, we present a detailed study of the effect of WO3 and Ni films in the presence of BP and BlueP-MDC nanomaterial layers on the sensitivity of a surface plasmon resonance (SPR) following the change in refractive index of the detection medium. Our nanostructure is based on the…

Quantum point-contact sensors: State of the art and prospects

Gennadii Kamarchuk, Olexander Pospelov, Volodymyr Vakula, Eric Faulques

We present generalized information on the new type of universal quantum detectors operating on the basis of Yanson point contacts. The properties and capabilities of quantum point-contact detectors are totally different from those of conventional sensors based on the principle of changing electric…

Adjusting Ag deposition power to improve corrosion resistance of ITO/Ag/ITO film for gate driver on array

Pingping Zhang, Zhiqiang Zhang, Xiang Yu, Lei Yang, Shuo Zhao, Rabah Boukherroub

Gate Driver on Array (GOA) can fulfil narrow-frame full screen of display device, but may encounter through-hole burnout during operation due to electrochemical corrosion under high-temperature and high-humidity environments. Through-hole burnout originates from vapor that penetrates display…

Spintronic terahertz emitters with integrated metallic terahertz cavities

Martin Mičica, Adrien Wright, Pierre Koleják, Geoffrey Lezier, Kamil Postava, Jacques Hawecker, Anna de Vetter, Jérôme Tignon, Juliette Mangeney, Henri Jaffrès, Romain Lebrun, Nicolas Tiercelin, Mathias Vanwolleghem, Sukhdeep Dhillon

Spintronic terahertz emitters (STEs), based on optical excitation of nanometer thick ferromagnetic/heavy metal (FM/HM) heterojunctions, have become important sources for the generation of terahertz (THz) pulses. However, the efficiency of the optical-to-THz conversion remains limited. Although…

Tilt-related alignment issues in miniature micromechanical on-wafer electrical probes composed of multiple flexible microcantilevers

Steve Arscott

Abstract Some new issues concerning the contacting and positioning of small electrical microelectromechanical systems (MEMS) probes based on multiple, flexible microcantilevers are presented here. A tilt error, associated with the lateral probe roll, means that contact touchdown occurs sequentially…
