Design Investigation of a Modified HMSIW Leaky Wave Antenna

International Journal of Information and Communication Technology Research, 2014
In this paper, a new leaky wave antenna (LWA) is introduced. The proposed antenna radiates through a dielectric aperture created by half mode substrate integrated waveguide (HMSIW) technique.

Design and Characterization of a Dual‐Mode Soft Robotic Flapping Propeller With Pneumatic Stiffness Modulation

Advanced Intelligent Systems, EarlyView.
A novel soft robotic propeller overcomes traditional efficiency‐flexibility tradeoffs via a hybrid pneumatic‐cable actuation strategy. This architecture enables active stiffness modulation with dual‐mode locomotion: tunable biomimetic swimming and earthworm‐inspired wriggling for confined spaces.

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire

Advanced Physics Research, EarlyView.
According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

Advanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.
