Efficient and rigorous analysis of leaky modes in 2-D EBG guiding structures

Résumé

Full-wave numerical approach for the analysis of leaky modes in periodic and bandgap structures composed of two-dimensional cylindrical inclusions has been proposed. A self-contained formulation is developed that uses a fast and accurate calculation of the lattice sums, which allows us for an appropriate choice of the spectral determination for each spatial harmonic. We analyze numerically a periodic chain composed of dielectric rods. Phase and attenuation constants are calculated and compared with those obtained by Fourier series expansion method with perfectly matched layers. A very good agreement is observed in a wide frequency range, while the computation time of the proposed approach is much faster.
