With the purpose to compare the physical features of the electromagnetic field, we describe the synthesis of optical singularities propagating in the free space and on a metal surface. In both cases the electromagnetic field has a slit-shaped curve a

The coherent-mode representation is a fundamental tool that helps us understand the processes of producing and propagating optical fields. In this work, such representation for self-imaging phenomena under partially coherent illumination is presented

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 differentia

The properties of optical surfaces generated by diffraction are studied analyzing the changes in the curvature function of the boundary condition. The study leads to establish a classification for the optical fields as elliptical, hyperbolical or par

We describe the synthesis of diffraction free beams and dark hollow beams with features easily tunable using a holographic transmittance. The hologram is generated by interfering two zero order Bessel beams with non-common axis. Spatial filtering tec

In general, optical fields have a spatially complex structure and they are capable of generating focusing regions. In the present paper, we solve the partial differential equation for the focusing regions as proposed by Berry and Upstill [Progress in
