# Applications and performance of a local conformal radiation boundary condition

@article{Lichtenberg1994ApplicationsAP, title={Applications and performance of a local conformal radiation boundary condition}, author={Bernd Lichtenberg and Yin-shang Liu and Je ery S. Reynolds and Kevin J. Webb and Douglas B. Meade}, journal={Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting}, year={1994}, volume={1}, pages={406-409 vol.1} }

The validity of the second order Bayliss-Turkel (BT) radiation boundary condition (RBC) representation is presented in terms of errors as a function of the order of a wavefunction representation and distance. Results for an aperture in a finite plane, which could be viewed as a wavelength scale optical lithographic mask, are given for the case of a conformal radiation boundary.<<ETX>>
