# Boundary element method for resonances in dielectric microcavities

@article{Wiersig2003BoundaryEM, title={Boundary element method for resonances in dielectric microcavities}, author={Jan Wiersig}, journal={Journal of Optics}, year={2003}, volume={5}, pages={53-60} }

A boundary element method based on a Green function technique is introduced to compute resonances with intermediate lifetimes in quasi-two-dimensional dielectric cavities. It can be applied to single or several optical resonators of arbitrary shape, including corners, for both TM and TE polarization. For cavities with symmetries a symmetry reduction is described. The existence of spurious solutions is discussed. The efficiency of the method is demonstrated by calculating resonances in two…
