✦ Synopsis

A two-level ΓΏnite element method is introduced and its application to the Helmholtz equation is considered. The method retains the desirable features of the Galerkin method enriched with residual-free bubbles, while it is not limited to discretizations using elements with simple geometry. The method can be applied to other equations and to irregular-shaped domains.

In electromagnetic field analysis, a systematic method of construction is presented for higher-order vector elements without respect to order. From the Helmholtz theorem, the vector basis functions are chosen. From the similarity with the scalar elements, the shape functions are determined by assign
