Dynamically tuneable helicity in twisted electromagnetic resonators
E. C. I. Paterson, J. Bourhill, M. E. Tobar +1
We report the generation of helical electromagnetic radiation in a microwave cavity resonator, achieved by introducing mirror asymmetry, i.e., chirality, through a controlled geome…

Distinct Berry Phases in a Single Triangular Möbius Microwave Resonator
E. C. I. Paterson, M. E. Tobar, M. Goryachev +1
We report the experimental observation of two distinct Berry phases ( and ) generated on the surface of a Möbius cavity resonator at microwave freq…
