Harnessing normal-shear coupling in metabarriers for deep sub-wavelength underwater noise control

Vinícius F Dal Poggetto, Marco Miniaci

Anthropogenic underwater noise poses a significant threat to marine ecosystems, disrupting key biological functions. Common mitigation strategies include enclosing noise sources within acoustic barriers. Current designs include locally resonant absorbers, which offer narrow-band performance, and…

0.53 mΩ.cm 2 /592 V High Breakdown Voltage GaN-on-Sapphire Schottky Diodes Without Edge Termination

Hugo Bouillaud, Beatriz Orfao, Etienne Okada, Yannick Roelens, Malek Zegaoui, Mohammed Zaknoune

In this letter, we report high-performance Pt/GaN quasi-vertical Schottky barrier diodes on sapphire substrate. With a 5 μm drift layer and a highly controlled fabrication process, the devices demonstrate an extremely low on-resistance of 0.53 mΩ.cm² while exhibiting a high breakdown voltage of 592…

Ultralow‐Dispersion Silicon THz Photonic Crystal Interconnects for Multichannel Datalinks

Nikhil Navaratna, Thomas Caiwei Tan, Pascal Szriftgiser, Guillaume Ducournau, Ranjan Singh

All-Silicon (Si) Terahertz (THz) interconnects are a key platform for next-generation on-chip communication, leveraging broadband photonics to connect reconfigurable electronics. Yet their potential remains largely unrealized, due to low reported data rates and a lack of systematic insight into the…

Chapter 9 - One open loop, two stubs, and two infinite leads

Housni Al-Wahsh, Eman Abdel-Ghaffar, Abdellatif Akjouj, Madiha Amrani, Leonard Dobrzyński

The present system is constructed out of one open loop of length L, two stubs of length , and two infinite leads. It is shown that the transmission properties of such a system depend on its bulk states localized in the whole structure and on infinite bound in continuum (IBIC) states. These IBICs…
