Propagation geometry and its effect on peak scintillation of intensity

Abstract

Extended Rytov Theory (ERT) is often interpreted as describing intensity scintillations as a function of volume turbulence strength. This approach can create difficulties when trying to compare theory to experimental results and wave optics simulations. Recent works in both areas show differences of a factor of two in the focusing regime where peak scintillation occurs. In this work, simulation campaigns are used to better understand the role of propagation geometry in terms of the first Fresnel zone size on peak scintillation.
