Analysis of beam wander effects for a horizontal-path propagating Gaussian-beam wave: focused beam case

Failure of the first-order Rytov approximation to properly predict the scintillation index of a large-aperture focused beam, or an uplink collimated (or focused) beam, has been discussed in several recent publications, which cite beam wander effects as the main reason for this failure. We use comput...
