In this paper, we have presented the process of beam steering and its advantages. Nowadays compact sized low profile antennas with planer structures and low fabrication cost have become essential. Therefore the antennas need to have enhanced gain and steerable radiation patterns. Therefore, beam steerable antennas have become very popular in modern day

A number of concepts using the principle of the refraction of light have been developed to steer light beams. Refractive beam steering concepts involve the use of optical wedges in order to deviate a light beam. This principle is ideally suited for steering laser light since dispersion is minimal due to the monochromatic nature of the laser.

2019 8th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2019
To reduce a risk of damage from an exposure and the guarantee of a stable receive level, in case of the system of a wireless LAN, a printed type inverted F antenna for beam-steering is designed and its characteristic is measured. A parasitic element having the optimized length and interval is attached in both sides of the printed type inverted F ...

Beam Steering with Linear Arrays
IEEE Transactions on Biomedical Engineering, 1983The principles and techniques of real-time imaging with phased array ultrasound scanners are reviewed. Topics include 1) the geometric optics of beam steering and focusing with a linear array in the transmit and receive modes; 2) limitations on image data acquisition due to ultrasound propagation velocity; 3) optical diffraction theory for linear ...

Beam Steering in the SLC Linac
IEEE Transactions on Nuclear Science, 1985In order to control emittance growth due to transverse wakefields it will be necessary to transport electrons and positrons through the Stanford Linear Collider (SLC) linac to within a hundred ?m of the centers of the linac irises. Beam centering will be accomplished using computer routines to read stripline beam position monitors and in turn correct ...

Traditional methods of beam steering of antennas have used phase as the primary variable. The intent of this research work is to revisit the idea of using amplitude rather than phase or mechanical motion to steer the beam and explore it as a possibility for some of today's needs.

Novel reflectarry for beam steering
Proceedings of the Twenty-Second National Radio Science Conference, 2005. NRSC 2005., 2005A class of novel reflectarray antenna topologies is proposed in this paper. The common features of these topologies are the presence of microstrip patches of similar size arranged into a regular lattice configuration on the top layer, and a periodic configuration of slots of variable size on the lower layer that are utilized to adjust the phase shift ...

Physics Antenna arrays have long been used for communication and sensing purposes. In the microwave and radio wavelength regime of the electromagnetic spectrum, arrays of antennas in which the phase and amplitude input to each element is varied can provide tailored beam profiles with controlled directionality.

Beam Steering in Anisotropic Metamaterials
Frontiers in Optics 2010/Laser Science XXVI, 2010We propose tunable anisotropic metamaterials consisting of silver nanorods and dielectric medium for applications to beam steering and demultiplexing. The tunability is achieved by changing the fill fraction and the properties of the dielectric medium.
