VI. On refraction at a cylindrical surface

Refraction at the Interface of a Lossy Metamaterial

The refraction phenomenon at the interface of an ordinary material and a lossy metamaterial has been investigated. For oblique incidence on the lossy metamaterial, the planes of constant amplitude of the refracted wave are parallel to the interface and the plane of constant phases make a real angle with the interface (real refraction angle). The real refraction angle and hence, the real refract...

Cylindrical Surface

In this paper we present a method to localize a cylindral surface with only one perspective view. Based on a priori knowledge we nd two axes in the image in order to obtain the three rotation angles between the cylindrical surface coordinate system and the camera coordinate system. Various applications of the proposed method are presented.

Analysis of Conformal Reflectarray on Cylindrical Surface

As the important case of conformal arrays, conformal arrays on cylindrical surfaces have been widely used in radar and communication systems. This paper explores the chances of designing conformal reflectarray on cylindrical platform. An extended array theory method is proposed in this paper for analyzing the radiation patterns of cylindrical conformal reflectarray. The radiation characteristic...

Cylindrical Surface Pasting

In the paper, we present cylindrical surface pasting, an extension of standard surface pasting that uses the surface pasting technique to attach two surfaces. The major issues discussed here are the domain mappings and the mapping of the feature control points. There are two types of domain mappings, depending on whether we paste a cylinder onto a NUBS sheet or another NUBS cylinder. The mappin...
