Abstract
We wish to analyze the EM scattering of the field produced by an incident plane wave then by an electric line source suspended above a double periodic infinite wire array with nonlinear inclusions in the presence of a pumping signal. In doing so we permit the possibility for phase conjugation of the transmitted signal as well as concurrent automatic proportional amplification control of the evanescent modes presented to the array. This investigation would permit the possibility of the construction of an ultra-thin lens with perfect or near perfect focusing capability and in refined methods for the creation of self-tracking antenna arrays. In addition the conditions under which the energy normally lost to specular reflection can be converted into energy in the phase conjugated signal, as well as the conditions for energy loss due to grating lobe formation under harmonic pumping conditions will be investigated. The proposed architectures represent a new class of phase conjugating artificial electromagnetic materials with potential for application in advanced microwave and millimeter wave systems.

Title | OBJECT IDENTIFICATION SYSTEM AND METHOD |
Description | An identification system and method of use thereof is provided, the system (1) comprising at least one transceiver cell (3) comprising an antenna component (7) which receives a part of an incoming signal (11) from an object (13), and a processor which processes the part of the incoming signal to extract identification information of the object, wherein the processor comprises a frequency downconverter/mixer unit comprising a coupler which produces first and second phase quadrature signals, a first mixer which receives the first signal and mixes it with the part of the incoming signal to produce a first output signal comprising object identification information, and a second mixer which receives the second signal and mixes it with the part of the incoming signal to produce a second output signal comprising object identification information, a phase shifter which receives the second output signal and adds a 90 degree phase shift to the signal to produce a phase shifted second output signal comprising the object identification information, a sideband signal filter which receives the first output signal from the frequency downconverter/mixer unit and receives the phase shifted second output signal from the phase shifter, and operates to produce a sideband signal of the part of the incoming signal which comprises the object identification information, and an object identification component which receives the sideband signal from the sideband signal filter, extracts the object identification information therefrom, and uses the object identification information to identify the object. |
