Topological transition in a nanowire medium and its radiative implication

M. S. Mirmoosa, S. Yu. Kosulnikov, C. R. Simovski

Published 2015-03-18Version 1

We reveal and study the topological transition in a metamaterial formed by parallel nanowires of polaritonic material. When the dispersion transits from the elliptic (epsilon-positive) to hyperbolic (epsilon-indefinite) regime, a very specific isofrequency surface arises which implies an extraordinary Purcell factor in spite of noticeable optical losses.
