Query: Surface plasmon resonance under conditions of electromagnetically
  induced transparency   A scheme for a surface plasmon resonance system under conditions of
electromagnetically induced transparency (EIT) is proposed. The system is
composed of three layers: a prism, a thin metal film, and a hybrid dielectric
consisting of EIT atoms and a background substance. A probe and a coupling
laser beam are input. Corresponding analytical formulas are derived for the
cases when one or both of the laser beams excite surface plasmon polaritons at
the metal/dielectric interface. Under resonance conditions, an extremely sharp
dip appears in the reflectivity-frequency spectrum of the probe field,
revealing new properties of two-dimensional EIT. The reflectivity is extremely
sensitive to shifts in the laser frequencies and atomic levels, and to
variations of permittivity of the substrate. This EIT-SPR system may to be used
for novel magnetometers and biosensors.
