In Section 2, we analyze the advantages using the backscatter
communication compared to using conventional methods of wireless communication and review the backscatter
A portion PS of the source flux invades the channel after crossing across the source-channel barrier in which a portion PC of the flux entered into the channel flowed across and depart from the drain and a left portion BC =1 - PC backscatters
from the channel and turn back into the source.
[beta] is defined as the ratio of scattered power [P.
TSA rolled out the backscatter
machines in October 2010 and subsequently authorized enhanced patdowns -- which could include the touching of breasts, buttocks and genitals -- for passengers unwilling to submit to those scanners.
units use very low power X-rays that bounce off skin and objects like Nerf-balls.
We used a combination of acoustic backscatter
measurements, video observations from a stereo-video drop camera (SDC), a remotely operated vehicle (ROV), and catch composition data from a modified bottom trawl to estimate abundances of rockfish species on Snakehead Bank.

The risks for any individual going through the X-ray backscatter
scanners are exceedingly small," Brenner said.
The SmartCheck Z Backscatter
Personnel Screening System was piloted at Phoenix Sky Harbor International Airport in February 2007.
The Model 318 X-Ray backscatter
sensor provides measurement performance that meets or exceeds the exacting requirements of plastics extrusion, converting, calendering, paper, nonwovens and textile applications, while being simple and inexpensive to install, operate and maintain.
is caused when x-ray radiation passes through the cassette, bounces and reenters the cassette.
In Rutherford backscattering spectrometry (RBS), energetic ions are directed at a sample and the energy spectrum from the backscatter
of ions is measured.
