On the analysis of backscatter traffic
39th Annual IEEE Conference on Local Computer Networks Workshops, 2014This work offers in-depth analysis of three different darknet datasets captured in 2004, 2006 and 2008 to provide insights into the nature of backscatter traffic. Moreover, we analyzed these datasets using two well-known open source intrusion detection systems (IDSs), namely Snort and Bro.

Surface roughness and backscattering
Optics Letters, 1996Surface roughness is normally considered to be the main cause of attenuation in intergrated-optics glass waveguides. Previous analyses have concentrated on scattering of light into the radiation field; in fact, depending on the roughness length scale, scattering can be predominantly in the backward direction, raising the question of how important the ...

Channeling and Backscatter Imaging
2016While the default imaging mode in HIM uses secondary electrons, backscattered helium or neon contains valuable information about the sample composition and structure. In this chapter, we will discuss how backscattered helium can be used to obtain information about buried structures and provide qualitative elemental contrast.

Coherent backscattering of neutrons
Physical Review B, 1987We study the effects of multiple scattering on the elastic incoherent cross section of neutron backscattering. The cross section is found to be enhanced within a narrow cone centered around the backscattering direction. An antienhancement of intensities is predicted, provided that spin-flip scattering is dominant.

Cognitive backscatter metasurface
2024 IEEE 25th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC)We study a novel spectrum-sharing paradigm for multicarrier cognitive radio (CR) networks, where the conventional primary system employs an orthogonal frequency-division multiplexing (OFDM) modulation scheme, whereas the secondary system is represented by an Internet of Things (IoT) metasurface that concurrently transmits data to a secondary receiver ...
