摘要：
Vector absorbing boundary conditions for doubly curved surfaces are presented, and their applicability to finite elements for scattering calculations are discussed, A performance study of these ABC's is carried out in terms of accuracy and computational requirement, and scattering patterns for several targets are included for validation purposes, It is found that accurate far-field results can be obtained by terminating the finite element mesh a fraction of a wavelength from the scattering structure.
