This article presents point-like, aperture averaged scintillation, and bit error rate(BER) performance of cylindrical-sinc Gaussian beam (CSGB). We model atmosphere utilizing random phase screen approach to be up to the complexity of source field expression. Our results indicate that it is possible to generate resistive CSGBs against turbulence considering point-like scintillation. Aperture averaged scintillation results show that all selected beams have lower scintillation index than Gauss beam. Major benefit of CSGBs is seen in BER evaluation in optical wireless communication systems. It is possible to decrease BER times lower than Gauss beam at nearly 13 dB signal to noise ratio(SNR).

The compressive strength of the basalt fibre SCC was diminished by 28% at 500°C. The splitting tensile strength of the SCC was increased by adding 0.25% of fibre. Considerable degradation in the flexural strength of fibrous SCC was seen at 300°C. Slant shear of hybrid concrete was highly affected by fibre content of overlay. Interfacial surface roughened by sand blast provided proper bond in hybrid sample.

In this paper, we analyze the intensity and phase changes of cosine beam(CB) propagating uniaxial crystal orthogonal to optical axis. Received field is derived based upon Huygens–Fresnel integration. Main objective of this paper is to present intensity and phase evolution of cosine beam in uniaxial crystals first time in the literature. However, behavior of other untraditional beams is studied, reaction of cosine beam against uniaxial crystal is not studied previously. We analyze the results considering source beam settings, crystal structure, and propagation distance. Our results indicate that matrix view in intensity profile evolves into straight lines along propagation axis. In other point of view, symmetric cosine beam has constant phase at close distance and periodic oscillation is observed at middle at far distance. We believe that results of this study will be beneficial for optical tracking and other optical applications.
