Abstract The metasurface based beam-steering devices with the advantages of large steering angles, arbitrary channels and ultra-compactness have played an important role for data allocation exchange in optical wireless communication. However, current communication systems are mainly on intensity modulation direct detection (IM/DD), which shows a relative lower transmission capacity, received si...

The results of a computer simulation laser beams focused by combined multichannel array system in the atmosphere are presented. Beam propagation on atmospheric paths is considered taking into account influence turbulence and time-dependent thermal blooming interactions. increase maximum intensity focal spot due to optimization initial power density emitting aperture estimated. It shown that sca...

Most ad hoc and sensor network research assumes idealised radio propagation models without considering fading and shadowing effects. Experimental results have shown that many well-designed protocols will fail simply because of fading and shadowing experienced in a realistic wireless environment. While fading and shadowing for radio propagation are well understood in the wireless communication c...

Multichannel images are the multiple image planes (channels) obtained by imaging the same scene using multiple sensors. The validity of multichannel restoration where both the within and between channel relations are incorporated has already been established using both stochastic and deterministic restoration filters. However, it has been demonstrated that stochastic multichannel filters are ex...
