- In this paper, we present a novel rotating magnetic dipole antenna, composed of two perpendicularly oriented helical coils, that can efficiently excite the unidirectional topologically protected surface waves in the bianisotropic metawaveguide (BMW) structure recently realized by Ma, et al., despite the fact that the BMW does not break time-reversal invariance.
