Patent ID: 7218090

Claim:
An apparatus for analyzing a spectral signal, comprising: a resonator board having multiple pairs of resonators and generally parallel wires arranged in a periodic matrix on a substrate; each of said resonators being interposed between said parallel wires and configured with a first segment and a second segment, said first segment including a first segment discontinuity and said second segment including a second segment discontinuity; said substrate, being composed of a dielectric material, supports said first segment and said second segment; said first segment and said second segment defining a boundary, said second segment, being spaced apart from said first segment, is disposed within said boundary; said spectral signal having a given wavelength; and an array of detectors, being disposed in proximity to said periodic matrix, each of said detectors being configured to reflect and focus an electromagnetic signal at a particular angle based on said given wavelength, said array being configured so that reflecting and focusing said spectral signal at a particular one of said detectors indicates a particular wavelength, each of said detectors being configured to measure an amplitude of said electromagnetic signal.
