For each homogeneous shell uncoupled radial equations for the longitudinal field components E<jats:sub>z<\/jats:sub> and H<jats:sub>z<\/jats:sub> are considered. Relationship between field solutions corresponding to core adjacent shells is established with the help of appropriate boundary conditions. Numerical results obtained with this method are presented and discussed, with special attention being focused on the analysis of the number of discretization steps necessary for achieving satisfactory core modeling. \u00a9 1993 John Wiley &amp; Sons, Inc.<\/jats:p>","DOI":"10.1002\/mop.4650060712","type":"journal-article","created":{"date-parts":[[2007,7,10]],"date-time":"2007-07-10T01:45:42Z","timestamp":1184031942000},"page":"426-431","source":"Crossref","is-referenced-by-count":2,"title":["An efficient method for analyzing graded\u2010index optical fibers"],"prefix":"10.1002","volume":"6","author":[{"given":"M.
