XHEMTs on Ultrawide Bandgap Single‐Crystal AlN Substrates
AlN/GaN/AlN XHEMTs [single‐crystal (“X‐tal”) high‐electron‐mobility transistors] are built on bulk AlN substrates with a 20 nm pseudomorphic GaN channel. This coherent epitaxial double heterostructure promises low‐defect, thermally efficient nitride electronics for next‐generation RF technology.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

This work shows the first proof‐of‐concept for fully self‐healing and stretchable coplanar waveguide (CPW) transmission line using printable electrically conductive liquid metal elastomer. RF performance was evaluated in frequency ranging from 1 to 6 GHz under uniaxial tensile strain up to 100%, after self‐healing, and for 1000 cyclic stretch‐release ...
