A Generalized Analysis of Multiple-Clad Fibers with Arbitrary Step-Indx Profiles and Applications
A generalized analysis of multiple-clad cylindrical dielectric structures with step-index profiles is presented. This analysis yields unified expressions for fields, dispersion equation and cutoff conditions for weakly guiding optical fibers with step-index but otherwise arbitrary profiles. The …

On the grammar of optative constructions
… aim of this dissertation is to present an analysis for so-called optative constructions, clauses that express a wish, hope or desire without containing a lexical item that means 'wish', 'hope' or 'desire'. A secondary aim is to contrast optative constructions with so-called polar …
