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 ( $+ \frac{2 π}{3}$ and $- \frac{2 π}{3}$ ) generated on the surface of a Möbius cavity resonator at microwave frequen…

Electromagnetic Helicity in Twisted Cavity Resonators

E. C. I. Paterson, J. Bourhill, M. E. Tobar +1

Through left- or right-handed twisting, we investigate the impact of mirror-asymmetry (chirality) of the conducting boundary conditions of an equilaterial triangular cross-section…
