Abstract
A finite element method is presented for directly determining the cutoff frequencies of a weakly guiding fibre, which can be of arbitrary inhomogeneity and cross-sectional shape. Errors of the method are discussed. Simple correction factors are given to improve the accuracy. © 1984 Chapman and Hall Ltd.
