Embedded RF Photonic Crystals as Routing and Processing Devices in Naval Aperstructures; Final technical rept. 14 Nov 2006-14 Jan 2008, Feb 2008

摘要

The ability to rapidly detect and process radio frequency (RF) signals is of extreme importance in the modern warfare environment. As the use of the electromagnetic spectrum continues to expand, the technical requirements necessary to maintain such a critical ability becomes very challenging; additional requirements such as miniaturization of the system, reduction in power consumption and the miniaturization of signatures places even more stringent requirements on an already pressing problem. To address these issues, we utilize advanced artificial materials - photonic crystals (PhCs) and meta- material - to construct a sensing head with minaturized antennas as RF receivers and embedded signal channelization for pre-processing. This sensor head can directly detect and process RF signals, significantly decreasing the response time on Naval platforms to potential threats. In this report, we present an overview of our work on theoretical design and experimental demonstration of miniaturized RF correlators and antennas based on meta- materials, as well as hybrid lattice PhCs and Schottky diodes for RF correlation and channelization.
