摘要
本文提出全域数值边界条件的概念和方法,并以两维散射问题有限元解法为例,说明它在开域电磁场问题偏微分方程数值解法中的应用。与各种相同类型的数值解法相比,本文方法在计算精度和效率诸方面均具有优势,并具有处理更加复杂的电磁场边值问题的能力。
A new concept and procedure of the Global Numerical Boundary Condition (GNBC) is presented in this paper. A finite element analysis of 2-dimensional scattering of complex scatterers is given as example, demonstrating the application of GNBC in numerical solutions of differential equations for the open-region electromagnetic field problems. The present numerical approach not only has advantages of high calculation precision and efficiency, but also can deal with more complicated problems such as multiobject scattering.
