## One-way waΒ¨e equation type boundary operators can ( ) produce instabilities in finite-differenceαtime-domain FDTD simulations. Such instabilities become acute when the order of the operator is three or higher. PreΒ¨ious efforts to stabilize these operators sacrificed either efficiency or accurac
We present two simple and effective schemes to formulate absorbing boundary conditions for time harmonic finite element analyses of waveguide structures. An impedance matching condition, applicable to single mode waveguides, is derived as well as an enhanced method for multi-modal wave propagation,
