Um limite de campo total/campo disperso (TF/SF) que é comumente usado no método de domínio de tempo de diferenças finitas (FDTD) para iluminar dispersores por ondas planas, é desenvolvido para uso no método de perfil de interpolação restrito (CIP) . Levando em consideração a dispersão numérica, o limite TF/SF quase perfeito pode ser alcançado, o que nos permite calcular campos incidentes contendo componentes de alta frequência sem campos dispersos fictícios. Primeiro de tudo, formulamos o limite TF/SF no esquema CIP. A relação de dispersão numérica é então revisada. Finalmente a dispersão numérica é implementada na fronteira TF/SF para estimar campos incidentes deformados. O desempenho do limite TF/SF quase perfeito é examinado medindo campos vazados na região SF, e o método proposto diminui drasticamente o vazamento em comparação com o limite TF/SF simples.

Abstract: A total-field/scattered-field (TF/SF) boundary which is commonly used in the finite-difference time-domain (FDTD) method to illuminate scatterers by plane waves, is developed for use in the constrained interpolation profile (CIP) method. By taking the numerical dispersion into account, the nearly perfect TF/SF boundary can be achieved, which allows us to calculate incident fields containing high frequency components without fictitious scattered fields. First of all, we formulate the TF/SF boundary in the CIP scheme. The numerical dispersion relation is then reviewed. Finally the numerical dispersion is implemented in the TF/SF boundary to estimate deformed incident fields. The performance of the nearly perfect TF/SF boundary is examined by measuring leaked fields in the SF region, and the proposed method drastically diminish the leakage compared with the simple TF/SF boundary.
