Journal ArticleDOI
Elliptically shaped ultra‐wideband patch antenna with band‐notch features
TL;DR: In this paper, a series of ultra-wideband antenna using an elliptically curved patch is investigated, where the band-notch feature is realized by cutting off a bended slot, which can be tuned.
Journal ArticleDOI
Ultrasensitive Transmissive Infrared Spectroscopy via Loss Engineering of Metallic Nanoantennas for Compact Devices
Jingxuan Wei,Ying Li,Yuhua Chang,Dihan Hasan,Bowei Dong,Yiming Ma,Cheng-Wei Qiu,Chengkuo Lee +7 more
TL;DR: Novel crooked nanoantennas are designed with a different paradigm based on loss engineering to overcome the above bottleneck, and paves the way towards cheap, compact and ultrasensitive infrared spectroscopy.
Journal ArticleDOI
Smart Doppler Cloak Operating in Broad Band and Full Polarizations.
TL;DR: In this paper, a smart Doppler cloak operating in broadband and full polarizations is reported, which consists of a time-modulated reflective metasurface and a sensing-feedback time-varying electronic control system.
Journal ArticleDOI
Versatile total angular momentum generation using cascaded J-plates
Yao-Wei Huang,Noah A. Rubin,Antonio Ambrosio,Zhujun Shi,Robert C. Devlin,Cheng-Wei Qiu,Federico Capasso +6 more
TL;DR: Cascaded J-plates can generate several single quantum number beams and versatile superpositions thereof and are demonstrated to produce vector vortex beams and complex structured light, providing new ways to control TAM states of light.
Journal ArticleDOI
