Programmable In‐Situ Interactions Between Resins and Photopolymerized Structures for Seamlessly Integrated Optical Manufacturing of Microlenses

Advanced Functional Materials, EarlyView.
This study presents a dynamic interaction between liquid resins and photopolymerized structures enabled by an in situ light‐writing setup. By controlling a three‐phase interface through localized photopolymerization, which provides physical confinement for the remaining uncured resin regions, the approach establishes a programmable pathway that ...

Reconfigurable plasma frequency selective surface

Proceedings of the 2025 International Symposium on Electromagnetic Theory - URSI EMTS 2025
This paper presents single- and double-layer reconfigurable frequency selective surfaces (FSS) for high-power microwave (HPM) shielding, utilizing plasma as an active element. Unlike conventional FSS, plasma-based design enables tunable filtering by adjusting plasma density or shape, reducing the need for extensive structural modifications.

Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

Advanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

High Rate/Low Complexity Space-Time Block Codes for 2x2 Reconfigurable MIMO Systems

, 2015
In this paper, we propose a full-rate full-diversity space-time block code (STBC) for 2x2 reconfigurable multiple-input multiple-output (MIMO) systems that require a low complexity maximum likelihood (ML) detector. We consider a transmitter equipped with
