摘要
作为开域电磁场问题偏微分方程解法的一个重要方面,本文提出导波致值边界条件的概念和算法。本文着重讨论二维的具有平面导体边界的导波系统的散射和辐射问题,并以此表明基于数值边界条件的偏微分方程的数值解法,将为波导-喇叭辐射器的准确分析开辟了新的理论途径。
As an important aspect of partial differential equation solutions of open-region electromagnetic field problems, the concept and algorithm of guided-wave global numerical boundary conditions are presented. Emphasis is placed on the two-dimensional guided-wave scattering and radiation analysis in the waveguides with plate-conducting boundaries. This analysis method can be readily expanded to cover many other guided-wave systems, leading to a new theoretical approach to the guide-horn like radiator analysis.
