Reconfigurable localized effects in non-Hermitian phononic plate

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

Skin effect is one of the intriguing phenomena exhibited by non-Hermitian wave systems. It reflects the localization of the modes at the boundaries of the structure. We demonstrated the skin effect for elastic waves propagating in a non-Hermitian phononic plate containing piezoelectric components...

Towards High Performance Fully Vertical GaN-on-Silicon PIN Diodes

Youssef Hamdaoui, Idriss Abid, Sondre Michler, Katir Ziouche, F Medjdoub

In this work, we demonstrate quasi and fully vertical PIN GaN on Si diodes with a low on state resistance of 0.35 mΩ.cm² and high average electric field of 1.82 MV/cm, which is favorably comparable to the state-of-the-art considering the absence of edge termination or field plates. The breakdown...

Securing Cognitive Radio Networks via Relay and Jammer-Based Energy Harvesting on Cascaded Channels

Deemah Tashman, Walaa Hamouda, Iyad Dayoub

Physical-layer security (PLS) is examined in this paper for an underlay cognitive radio network (CRN). Two secondary users (SUs) interact through a relay that is equipped with multiple antennas and harvests energy from the SU transmitter's messages via a power splitting (PS) approach....

Power Handling of GaN Schottky Diodes on Semi-Insulating Ammonothermal GaN Substrate at 94 GHz

Mahmoud ABOU DAHER, Hugo Bouillaud, Pawel Prystawko, Michal Bockowski, Etienne Okada, Malek Zegaoui, Guillaume Ducournau, Yannick Roelens, Mohammed Zaknoune

In this paper, we report electrical results and handling power results of different Schottky diodes based on 620 nm of n- Gallium Nitride (GaN) fabricated on ammonothermal GaN substrate. The breakdown voltage obtained is 115 V/µm. Diodes held 29.6 dBm at zero bias and we detected an output voltage...
