Radiation of Spatially Incoherent Noise: Circular and Rectangular Plane Sources.
Abstract
The concept of spatially incoherent (SI) radiation has been applied to extended sources. The fields of SI-radiating circular disks and rectangles have been calculated for uniform radiation and for a square law decrease (of power radiated per unit area) toward source edges. The shaded disk has a field much like that of a uniform disk of diameter 20% less. All fields show regions with zero deviation from the (inverse square law) field of a point source radiating from the center. Programs in BASIC are provided for detailed calculations of the actual deviations at any field point. (Author)
