Due to the inherent vulnerability of wireless transmission to eavesdropping, con- dentiality arises as a challenging issue especially for future wireless networks because of their unique requirements. To cope with this, ...

Quality of a digital image depends on several factors operative during the image formation process, e.g. sensor defects, sensor dynamic range, poor spatial resolution,lens distortion, camera shake and object motion. This ...

Interference and random behavior of the propagation environment are the main impediments to serve a broad range of applications and use-cases in modern communication systems. Although conventional orthogonal multiple ...

The inherent broadcast characteristics of wireless communication make it vulnerable to passive eavesdropping. Conventionally, security techniques in the upper layers like cryptography-based techniques have been employed ...

In this dissertation, a simple, accurate, and efficient solution is presented for the problem of scattering from a chiral cylinder of arbitrary cross-section above a ground plane. Both TM and TE excitations are considered. ...

A simple numerical solution for electromagnetic scattering from a two dimensional (2-D) homogeneous chiral cylinder of arbitrary cross-section placed above a dielectric half-space is presented. The surface equivalence ...

Application richness and the level of technological development have increased extraordinarily in the last ten years in the field of modern wireless communications. There is a need for a flexible communications infrastructure ...
