This article presents the design, simulation, and experimental validation of an ultra-compact 3-dB microstrip coupler with significantly reduced dimensions. The primary objective of this study is to ...

This paper presents an ultracompact tunable device for power splitting and switching by tuning the Fermi energy level of monolayer patternless graphene underneath a slotted multimode interference (MMI ...

Sound engineering: The new device is a chip-based single-phonon directional coupler that carries out controllable phonon splitting. It could enable microscopic on-chip routers and splitters that link ...
