Diffractive Synthesis of Multipole Interference States Using Low‐Index Mesoscale Dielectric Structures

open access: yesAdvanced Photonics Research, EarlyView.
Multipole interference (MPI) plays pivotal roles in electromagnetics. In optics, it has been realized typically with the Mie resonance in high‐index, deep‐subwavelength‐scale dielectric resonators. A new, diffraction‐based MPI scheme is proposed and demonstrated with low‐index, mesoscale dielectric structures.

Analysis of Electronic Structure and Binding Energy in Five‐Electron GaAs/AlxGa1‐xAs Quantum Dots Under Penetrable Confinement Potential

open access: yesAdvanced Theory and Simulations, EarlyView.
This study analyses the electronic structure of five‐electron spherical quantum dots with penetrable confinement potential. Spatial confinement and the influence of potential barrier height give rise to the unique properties of quantum dots. These effects lead to profound changes in their energy spectra and optical properties which play a key role in ...

A Convoy of Magnetic Millirobots Transports Endoscopic Instruments for Minimally‐Invasive Surgery

open access: yesAdvanced Science, EarlyView.
The first electrocautery procedure performed by a team of millirobots (TrainBots) is presented. Enhanced with optimized feet, millirobots form a convoy to facilitate the collaborative transportation of wires and catheters through biological lumens, e.g. bile ducts. It opens up the possibility of using a team of mini‐robots in future endoscopic surgery.

A Membrane Magnetoelastic Generator for Acoustic Energy Harvesting

open access: yesAdvanced Science, EarlyView.
This study introduces a thin, flexible, and water‐/dust‐proof membrane magnetoelastic generator that converts acoustic energy into electricity through the coupling of giant magnetoelasticity and electromagnetic induction. Featuring a skin‐like modulus, low impedance, and high output current density, this fundamentally new platform technology can ...
