Polymer-dispersed liquid crystals (PDLCs), comprised of submicron-sized LC droplets
embedded in a continuous polymer matrix, have been the subject of interest for scientists …

To address the massive spike in uncertainties triggered by the coronavirus disease (COVID-
19), there is an ever-increasing number of national governments that are rolling out contact …

In this paper, we report the design, preparation and properties of epoxy-mercaptan
polymer/nematic liquid crystal (LC) composites with electrically switchable optical …

A wavelength-selective, two-stage polymerization of acrylate-thiol for the formation of
polymer dispersed liquid crystal (PDLC) films is developed. Via this method, the PDLC with …

A novel bypass-embedded multilevel multicell inverter is proposed with manipulation of
bidirectional flow of currents targeting electric motor drives and regenerative braking (battery …

An all-optically driven microwave phase shifter is designed and experimentally
demonstrated for 1–10 GHz. The proposed optical addressing is realised in nematic liquid …

Conventional models for lensless imaging assume that each measurement results from
convolving a given scene with a single experimentally measured point-spread function …

Spectral imaging is a fundamental diagnostic technique with widespread application.
Conventional spectral imaging approaches have intrinsic limitations on spatial and spectral …

Millimetre-wave beam-steering distortions are due mainly to unbalanced feeding amplitudes
among the delay lines network. To compensate for this, active amplifiers or attenuators are …
