چکیده
We formulate the photonic band structure calculation of any lossless dispersive photonic crystal and optical metamaterial as a Hermitian eigenvalue problem. We further show that the eigenmodes of such lossless systems provide an orthonormal basis, which can be used to rigorously describe the behavior of lossy dispersive systems in general.

Computing photonic band structures by Dirichlet-to-Neumann maps: the triangular lattice
An efficient semi-analytic method is developed for computing the band structures of two-dimensional photonic crystals which are triangular lattices of circular cylinders. The problem is formulated as an eigenvalue problem for a given frequency using the Dirichlet-to-Neumann (DtN) map of a hexagon unit cell. This is a linear eigenvalue problem even if the material is dispersive, where the eigenv...
متن کاملThree-dimensional dispersive metallic photonic crystals with a bandgap and a high cutoff frequency.
The goal of this work is to analyze three-dimensional dispersive metallic photonic crystals (PCs) and to find a structure that can provide a bandgap and a high cutoff frequency. The determination of the band structure of a PC with dispersive materials is an expensive nonlinear eigenvalue problem; in this work we propose a rational-polynomial method to convert such a nonlinear eigenvalue problem...
متن کاملAdaptive finite element methods for computing band gaps in photonic crystals
In this paper we propose adaptive finite element methods for computing the band structure of 2D periodic photonic crystals and of photonic crystal fibres, modelled as spectral problems for Maxwell’s equations under either TM or TE polarisation. With the application of the Floquet transform the problem of computing the spectrum can be reduced to the computation of the discrete spectra of each me...
متن کاملAnalyzing Photonic Crystal Waveguides by Dirichlet-to-Neumann Maps
An efficient numerical method is developed for modal analysis of twodimensional photonic crystal waveguides. Using the Dirichlet-to-Neumann (DtN) map of the supercell, the waveguide modes are solved from an eigenvalue problem formulated on two boundaries of the supercell, leading to significantly smaller matrices when it is discretized. The eigenvalue problem is linear even when the medium is d...
متن کاملBandgap optimization of two-dimensional photonic crystals using semidefinite programming and subspace methods
In this paper, we consider the optimal design of photonic crystal band structures for twodimensional square lattices. The mathematical formulation of the band gap optimization problem leads to an infinite-dimensional Hermitian eigenvalue optimization problem parametrized by the dielectric material and the wave vector. To make the problem tractable, the original eigenvalue problem is discretized...
