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 by χ^(2) trapping
Optics Letters, 1995We show numerically the mutual dragging and locking together of intense fundamental and second-harmonic light beams propagating in second-order nonlinear media, and we discuss the potential applications of such effects for the steering of beams by spatial phase modulation of the input signals.

2017 International Conference on Innovations in Information, Embedded and Communication Systems (ICIIECS), 2017
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

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 ...

SPIE Proceedings, 2004
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.

Dynamic Beam Steering With Reconfigurable Metagratings
IEEE Transactions on Antennas and Propagation, 2020Metagratings have recently shown promising features for wavefront manipulation, overcoming the efficiency limitations of gradient metasurfaces and their demanding fabrication requirements. Extreme functionalities, such as perfect anomalous reflection and refraction, focusing, and holography, have been proposed and tested. However, most of the developed

Electronic beam steering of shock waves
Ultrasound in Medicine & Biology, 1995Shock-wave generators are now currently used for the treatment of renal stones. In all these generators the focal zone is determined by their geometrical parameters. We propose, for the first time, a piezocomposite shock-wave generator with electronic focusing. The system is composed of a two-dimensional array and its electronic hardware.

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.
