Possible realization of directional optical waveguides in photonic crystals with broken time-reversal symmetry. [PDF]
Physical Review Letters, 2005 We show how, in principle, to construct analogs of quantum Hall edge states in "photonic crystals" made with nonreciprocal (Faraday-effect) media. These form "one-way waveguides" that allow electromagnetic energy to flow in one direction only.

Temporally and zonally varying atmospheric waveguides – climatologies and connections to quasi-stationary waves [PDF]
Weather and Climate DynamicsAtmospheric waveguides have been linked to amplified quasi-stationary Rossby waves and thus to extreme weather events in the mid-latitudes. Here, we compare different methods of calculating temporally and spatially varying waveguides, including different
