TL;DR: In this article, the authors proposed a novel inner coordinates expression for the asymptotic surface-to-edge integral reduction of physical optics and fringe wave currents, leading to explicit forms of the physical optics components; fringe wave components and geometrical theory of diffraction equivalent edge currents without false singularities.
Abstract: The authors propose a novel inner coordinates expression for the asymptotic surface-to-edge integral reduction of physical optics and fringe wave currents. These coordinates lead to explicit forms of the physical optics components; fringe wave components and geometrical theory of diffraction equivalent edge currents without false singularities. They have an advantage in predicting finite diffracted fields for arbitrary aspects of illumination and observation including shadow and reflection boundaries. The numerical check assures the validity of these currents.

TL;DR: In this paper, an analysis theory of the shape-beam doubly curved reflector antenna is described, which utilizes a computer solution approach to achieve an accurate knowledge of the principal and cross-polarization elevation and azimuth patterns by numerically integrating the field contributions over the entire reflector surface.
Abstract: An analysis theory of the shaped-beam doubly curved reflector antenna is described. The analysis computes the far-field patterns by calculating the current density distribution on the nonanalytic surface that the shaped-beam doubly curved reflector presents using the physical optics vector approximation. The presented theory utilizes a computer solution approach to achieve an accurate knowledge of the principal and cross-polarization elevation and azimuth patterns by numerically integrating the field contributions over the entire reflector surface. A comparison of the computed and measured principal plane patterns is shown.

TL;DR: The correlation singular optics (CSO) as mentioned in this paper is a branch of this area of investigation, which can be referred to as the correlation singular optical field (CSOF) field.
Abstract: Singular optics has been recognized as separate important branch of modern physics about 15 years ago. Actually, along this period it was developed as coherent singular optics. Fundamental properties of phase singularities and the most important regularities governing the formation of singular skeletons of the field (such as sign principles) have been established both for scalar (uniformly polarized) and for vector (spatially non-uniformly polarized) monochromatic optical fields. Development of coherent singular optics continues. The most interesting and promising event of the last years, especially since 2002, consists in the tendency to expand the singular optical principles on the field of partially coherent light fields. In this context, physically new singular optical concepts are derived, new experimental instrumentation is developed, and new promising applications of the singular optical approaches are elucidated. Analysis of last achievements in the field of singular optics leads to the conclusion on coming into being of new branch of this area of investigation, which can be referred to as the correlation singular optics. It is remarkable that fruitfulness of this new R&D direction is essentially determined by the concepts and results of classical wave optics, which were developed irrespective of the singular optical paradigm.© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering.
