The analytical expressions of radial and the longitudinal components of scintillation index
are derived in weak oceanic turbulence. The effects of off-axis distance, propagation …

The wireless optical communication systems attract significant research and commercial
interest the last few years due to their capability of achieving wireless communications with …

We present on-axis, aperture averaged scintillation, and bit error rate performance of
Mathieu–Gauss beams (MGB). We model atmosphere utilizing random phase screen. Our …

Scintillation index is examined for annular optical beams in a strong atmospheric medium of
a slant path. On-axis scintillations have small-and large-scale components and are …

We study scintillation and bit error rate performance of sine hollow beam in turbulent
atmosphere. Since source field expression involves higher order term, we model …

In this paper, we study on-axis (point like) scintillation, change in scintillation index
depending on receiver aperture radius, and bit error rate evaluation of Lommel beam …

Propagation properties represent a critical aspect of laser beams utilized in free space
optical (FSO) communications. We examined the evolution characteristics of the electric field …

Starting from the second order moment formulation for multi-beam incidence, field
correlations at the receiver plane of flat-topped Gaussian and annular beams are found in …

Propagation properties of astigmatic sinh-Gaussian beams (ShGBs) with small beam width
in turbulent atmosphere are investigated. Based on the extended Huygens–Fresnel integral …

Intensity fluctuations of a crossbeam are evaluated in weak atmospheric turbulence. A
crossbeam is defined as two asymmetrical Gaussian beams oriented perpendicular to each …
