In this article, we propose a new numerical method for the computation of electromagnetic modes in an optical fibre. The main difficulty lies in the fact that we have to solve an eigenvalue problem posed in 1. We reduce the problem to a disc with the help of the introduction of non-local boundary op

The problem of the computation of the matrix elements Z ( v , v ' ; k ) = [ q U ( r ) ( r -rJkqUr(r)dr, is considered when q u ( r ) and q J r ) are eigenfunctions related to a diatomic potential of the RKR type (defined by the coordinates of its turning points Pi with polynomial interpolations). Th
A practical algorithm is described for the computation of the transition matrix and its integral of a timeinvariant state-space system. It is based on the partial Taylor expansion of the matrices, and methods for reducing computations and increasing accuracy are given.
