The modal method based on Gegenbauer polynomials (MMGE) is extended to the case of
bidimensional binary gratings. A new concept of modified polynomials is introduced in order …

Many engineered photonic devices can be decomposed into parts where the material
properties are independent of one or more spatial variables. Numerical mode-matching …

The choice of factorization rule can strongly affect the convergence of solutions to Maxwell
equations based on the orthogonal expansion of electromagnetic fields. While this issue has …

The polynomial modal method (PMM) is one of the most powerful methods for modeling
diffraction from lamellar gratings. In the present work, we show that applying it to the so …

In this paper, the electromagnetic field scattered by a cylinder with an arbitrary cross section
is computed using a domain decomposition method in which the structure under …

Depuis 2004, il a été montré qu'une sphère diélectrique de quelques longueurs d'onde
pouvait concentrer une onde électromagnétique en champ proche en un faisceau ayant une …

The work presented here focuses on the numerical modeling of cylindrical structure
eigenmodes with an arbitrary cross section using Gegenbauer polynomials. The new …

We present a new semi-analytical formulation for diffraction by structured cylinders. A
pseudo-spectral method is used to solve the Maxwell equations written in curvilinear …
