4 September 2018 Singular features of the diffraction field
Author Affiliations +
Diffraction fields many times can generate a focusing region, we describe the focusing region associated with symmetric transmittances, analyzing its associated phase function. We show that some generic features, it can be obtained from a differential equation for a focusing geometry, which is obtained through angular representation for diffraction fields, the diffraction field presents a new focusing region whose geometry and spatial evolution can be described with the analysis of the phase singularities avoiding the integral diffraction calculation.
