同时提高了计算精确度和速度.

Abstract

To solve the problem of determining the electromagnetic fields near material interfaces

we have proposed coupling the domain decomposition method with radial basis functions(RBFs) mesh-free.Discontinuities in the derivatives of the fields are not easily modeled with these infinitely smooth functions.To alleviate this difficulty

the use of special functions near material interfaces has been proposed but these functions can be difficult to implement

and thus cumbersome to use.We also applied the m...
