Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

open access: yesAdvanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Microwave Monitoring by Compact Carbon Nanotube Photo‐Thermoelectric Sensors Beyond the Diffraction Limit Toward Ultrabroadband Non‐Destructive Inspections

open access: yesAdvanced Sensor Research, EarlyView.
This work overcomes long‐standing crucial technical difficulties in miniaturizing micro‐wave detectors, caused by the longer‐wavelength diffraction limit, with carbon nanotube (CNT) film photo‐thermoelectric sensors. The CNT film sensor exhibits sensitive micro‐wave detection operations with signal‐to‐noise ratios over 1400 at compact device sizes ...

The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples

open access: yesAdvanced Theory and Simulations, EarlyView.
FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,

Boron‐Based Functional Additives Enable Solid Electrolyte Interphase Engineering in Calcium Metal Battery

open access: yesBatteries &Supercaps, Volume 6, Issue 1, January 2023., 2023
Engineering of Ca‐based SEI using boron‐based additives is investigated and their morphology, composition, and properties are thoroughly characterized. The presence of boron‐crosslinked polymeric matrices in the passivation layer plays a major role allowing for Ca plating.

A Riesz representation theorem for cone-valued functions

open access: yesAbstract and Applied Analysis, 1999
We consider Borel measures on a locally compact Hausdorff space whose values are linear functionals on a locally convex cone. We define integrals for cone-valued functions and verify that continuous linear functionals on certain spaces of continuous cone-
