A correlator sensor chip based on the integration of meta-materials and photonic crystals

In this paper, we utilize advanced artificial materials, namely, photonic crystals (PhCs) and meta-materials, to construct a sensing head with miniaturized antennas as detecting devices and embedded signal channelization for preprocessing. We experimentally demonstrated miniaturized antennas based on meta-materials, as well as, hybrid lattice PhCs and Schottky diodes for RF channelization. To further decrease the size of the system, we also present our initial design and simulation results for a PhC slow wave delay line, which also functions as a waveguide to the channelized signals.
