Beam-steering accuracy and polarisation agility in near-field antenna systems
, 2022 With a substantial part of the world’s population still not connected to the internet, satellite-on-the-move (SOTM) communication is the choice of connectivity in regions where terrestrial communication systems are not available.

Design of Compact Beam-Steering Antennas Using a Metasurface Formed by Uniform Square Rings
IEEE Access, 2018 In this paper, we propose two designs of slot-fed metasurface antenna for beam steering applications. Both designs have the same two-layer stacked configuration consisting of either a single-slot or a double-slot radiator and a metasurface superstrate ...

Two-Dimensional Dynamic Beam Steering by Tamm Plasmon Polariton
Photonics, 2023 The dynamic steering of a beam reflected from a photonic structure supporting Tamm plasmon polariton is demonstrated. The phase and amplitude of the reflected wave are adjusted by modulating the refractive index of a transparent conductive oxide layer by

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Light recycling beam steering on a DMD lidar
, 2018 Spatial light modulators (SLMs) that operate in a phase modulation mode enable beam steering with higher diffraction efficiency compared to amplitude modulation mode, thus potentially be used for an efficient beam steering with no moving part. Currently,

A beam steering antenna based on Fresnel zone plate radome
Electronics Letters, 2021 In this study, a beam steering antenna was presented, comprising patch antenna and two layers of Fresnel zone plate (FZP). One of the FZP was a fixed structure, the other was a 1‐D collapsible radome with alternately deployed metal strips covering and ...

360° beam-steering reconfigurable wideband substrate integrated waveguide horn antenna
, 2016 A novel beam-steering reconfigurable substrate integrated waveguide (SIW) horn antenna is presented. By employing p-i-n diodes as tuning mechanisms, the states of copper posts of the SIW horn can be electronically controlled.
