For keeping energy at a finite level, the mode amplitude along the radial coordinate is modulated by a decreasing exponential function. A peculiar property of such modes is that they exist in the Laplace transform's realm. After a brief discussion of the near-zone, we pass to the far-zone, where the field can be evaluated in closed form. The corresponding features of the intensity distribution are discussed. eng https://creativecommons.org/licenses/by/3.0/es/ open access Atribución 3.0 España Modal analysis of pseudo-Schell model sources journal article
