An Overview on Backscatter Communications
Journal of Communications and Information Networks, 2019As a key low-power communication technique, backscatter communications exploits the reflected or backscattered signals to transmit data, where the backscattered signals can be the reflection of ambient radio frequency (RF) signals, the RF signals from the dedicated carrier emitter or the signal photons in the non-classical quantum entangled pairs, etc.

Medical Physics, 1980
Although electron backscatter has been a subject of investigation for many years, both theory and experimental data are sparse. This article examines the available data and shows that a large percentage of both the theoretical and experimental values fit an empirical relationship for a large range of electron energies.

Backscatter directivity and integrated backscatter power of arterial tissue
The International Journal of Cardiac Imaging, 1991A 27 MHz transducer, mounted on an ultrasonic microscope, was used to quantify the dependence of backscatter power on the angle of incidence of arterial vessels. Due to variations in the angle of incidence significant variations in backscatter power were found in the intima, the muscular and elastic media, the adventitia and the external elastic lamina.

Coherent backscattering spectroscopy
Optics Letters, 2004Coherent backscattering (CBS) of light in random media has been previously investigated by use of coherent light sources. Here we report a novel method of CBS measurement that combines low spatial coherence, broadband illumination, and spectrally resolved detection.

Backscatter signatures of knots
Optics Letters, 1995We examine the knottedness of a structure through optical or electromagnetic wave scattering as a first step in the investigation of scattering from and propagation through knotted media. Initial investigations demonstrate that the handedness of knots and the degree of knottedness can be deduced from the backscatter signature for the examples ...
