| Abstract: | A general B-spline finite element method in parametric form is presented in this paper ,and the idea of truncating in the parametric field or transformed field is also described further. The general B-spline functions and the steps of operating are introduced firstly, then as an example.,the current distributions along one arm of two-arm conical log-spiral antenna are calculated with the third power B-spline finite element method,which confirm the efficiency of the method. |
