AB  - Depositing very thin organic films on the surface of arrays of asymmetric 
      split-ring resonators (A-SRRs) produces a shift in their resonance spectra that 
      can be utilized for sensitive analyte detection. Here we show that when 
      poly-methyl-methacrylate (PMMA) is used as an organic probe (analyte) on top of 
      the A-SRR array, the phase and amplitude of a characteristic molecular Fano 
      resonance associated with a carbonyl bond changes according to the spectral 
      positions of the trapped mode resonance of the A-SRRs and their plasmonic 
      reflection peaks. Furthermore, we localize blocks of PMMA at different locations 
      on the A-SRR array to determine the effectiveness of detection of very small 
      amounts of non-uniformly distributed analyte.
