Recently introduced surface plasmon toy black hole model has been extended in
order to emulate a rotating black hole (Kerr metric). Physical realization of
this model involves a droplet of an optically active liquid on the metal
surface which supports propagation of surface plasmons. Such droplets are shown
to exhibit giant optical activity in the frequency range near the surface
plasmon resonance of a metal-liquid interface.Comment: 4 pages, 4 figure
