Abstract

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.
