Abstract

A new method based on the boundary element method (BEM) is developed to calculate high quality factors of whispering-gallery modes by studying the Poynting vector. The method has high calculation accuracy, which exceeds traditional methods with the same PC computation resource. To demonstrate the feasibility of the present method, circular and quadrupole microcavities are investigated with this method and compared with the results by analytical and finite element method (FEM) results, respectively.
