Coupled-resonances can be used in applications that include, but are not limited to, surface-enhanced infrared
spectroscopy (SEIRS), surface-enhanced Raman spectroscopy (SERS), biosensing, and index sensing. Fano resonance in
analogue plasmonic systems has been described as the coupling of a bright (superradiant) mode and a dark (subradiant)
mode via the near field.Dark and bright mode interactionsareinvestigated with the use of a Fano resonant metamaterial
(FRMM) where the metamaterial is a dual nano-slot metasurface on a silicon cavity. The FRMM is numerically
simulated using Ansys High Frequency Structure Simulator (HFSS). The FRMM is coupled to the carbon double bond
in polymethyl methacrylate (PMMA) to demonstrate mode splitting and signal enhancement. Then the dual nano-slot is
compared to the complementary dual nano-rod configuration.
