Beckett, D.H., Cox, S.J., Generowicz, J.M., Hiett, B.P., Molinari, M. and Thomas, K.S. (2002) Application of finite element methods to photonic crystal modelling At 4th International Conference on Computation in Electromagnetics, CEM 2002. 08 - 11 Apr 2002. 2 pp, pp. 15-16.

Record type: Conference or Workshop Item (Paper)


Photonic crystals are materials with periodically modulated dielectric constant, through which certain frequencies of electromagnetic radiation cannot propagate; the luminary analogues of semiconductors. The modes admitted by photonic crystals can be investigated effectively using the finite element method with the assistance of the Bloch-Floquet theorem, by considering a unit cell of the material and imposing periodic boundary conditions. Along with the Dirichlet and metric matrices, a third type of elemental matrix emerges. The types of results that are of interest to photonic crystal manufacturers are introduced and presented; in this context, the benefits of using subspace iteration techniques to solve the eigensystems are discussed.
