    "abstract": "Adaptive finite elements are the method of choice for accurate simulations of\noptical components. However as shown recently by Bienstman et al. many finite\nelement mode solvers fail to compute the propagation constant\u0027s imaginary part\nof a leaky waveguide with sufficient accuracy. In this paper we show that with\na special goal oriented error estimator for capturing radiation losses this\nproblem is overcome.",
