Exploitation of Omnidirectional Reflectivity
Abstract
In this final report, we have summarized the progress made during the period of September 1. 2002-September 30, 2003. We derive the integral equations for (electric fields propagating in a fiber of arbitrary cross section and arbitrary refractive index. Mathematical analysis of conventional optical fibers is rich and widely available in literature, for example 3, 9, 11 and references therein. It helps the advancement of optical fiber industry in understanding and designing fibers for data transport and telecommunications. In knowledge, there is little of rigorous mathematical study of Bragg fibers due to the fabrication difficulty. Recently, the publications of A dielectric omnidirectional reflector 4, An all-dielectric coaxial wave guide 8, and External reflection from omnidirectional dielectric mirror fibers 7 in Science report successful fabrications of omnidirectional reflectors and multi-layered fibers for optical wavelengths. These articles create a new interest in studying low-loss Bragg fibers at microwave and millimeter wavelengths for radar applications. From previous examples in Section 4, multi-layered fibers of radii between 7 mm and 19 mm concentrate wave propagation within their air core for wavelengths in the microwave range.
