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

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,

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

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.

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.
