Wideband Wearable Antenna for Biomedical Telemetry Applications
IEEE Access, 2020 This paper presents a wideband, low-profile and semi-flexible antenna for wearable biomedical telemetry applications. The antenna is designed on a semi-flexible material of RT/duroid 5880 ( $\epsilon _{r} = 2.2$ , tan $\delta = 0.0004$ ) with an overall ...

Advanced Functional Materials, EarlyView.Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Folded Chirp-Rate Shift Keying Modulation for LEO Satellite IoT
IEEE Access, 2019 In the low earth orbit (LEO) satellite Internet of Things (IoT), the IoT devices can be distributed in remote areas (e.g., desert, ocean, and forest) for some special applications, where they are unable to have direct terrestrial network accesses and can

Slanted-eye featured forbidden bands in a water channel with undulated sidewalls
Results in Physics, 2021 Resonances induced by structure periodicity can always lead to frequency gaps, which are forbidden bands of propagating waves. Besides the traditional Bragg gaps, non-Bragg gaps have been found in periodic waveguides for years, which have been proved to ...
