Real Time Detecting and Processing Signals by an Integrated Sensor Chip Based on Meta-materials and Photonic Crystals
Abstract
This effort has been realized to advance the U.S. Navy's vision of an integrated ship topside, where the elements detecting, guiding, processing, and radiating signals become an integral part of the ship's structure. The integrated signal processing structure must also meet structural and design requirements: signature control, isolation, weight reduction, and a low observable (LO) profile. To fulfill these requirements, several different technological phases are used including dielectric waveguides and transitions, radiating grating structures, and advanced artificial materials, namely, photonic crystals (PhCs) and meta-materials. The dielectric waveguides, and PhC devices are electromagnetically transparent, leading to a significant reduction of the scattering cross-section, i.e., better signature control. Also, the PhC structure provides very good signal isolation and is lightweight while maintaining structural soundness. Spatial light modulators with tunable metamaterials allow for signal processing while maintaining a LO profile. To support integrated signal detecting and processing system, designs, simulations, and experimental results for the years 2008-2012 are presented.
