Data for "Azimuthal confinement: the missing ingredient in understanding confinement loss in antiresonant, hollow-core fibres"

This dataset contains all the underlying data used in Figures 4 to 7 of the associated paper. The paper is a theoretical and computational analysis of the guidance mechanism and confinement loss in antiresonant, hollow-core optical fibres. The data includes the results of both simplified theoretical models and large scale numerical calculations for a set of cladding structures that demonstrate the effects of azimuthal confinement.
