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…
Euclid VI. NISP-P optical ghosts
Euclid Collaboration, K. Paterson, M. Schirmer +309
The Near-Infrared Spectrometer and Photometer (NISP) onboard Euclid includes several optical elements in its path, which introduce artefacts into the data from non-nominal light pa…
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 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…
