Abstract

We theoretically study the two-dimensional (2D) dipole radiation near the interface of a magneto-optical material and a plasmonic metal. We show that an asymmetric radiation pattern occurs due to time reversal symmetry breaking, which is influenced by the “one-way” surface plasmon wave propagating at the interface of the two media. Unlike a normal reciprocal dipole, the transmission and reception radiation patterns of this dipole are different and both asymmetric.
