Abstract: This paper proposes an extension into interpolations concerning basic element in three-dimensional finite element method (FEM) using the tetrahedric elements. These later are based on vector-edge element which is proposed for the global analysis of waves guided structures. However, this new computational technique will be presented when the electromagnetic differential equations are incorporated into interpolations. Multiscalets used in the finite element method (MS-FEM) for electromagnetic waves problems are presented. In first approach, multiscalets with higher order multiplicity r=3, are employed as basis functions. In second approach, new discretization is used to model a microstrip line; here we use the cubic element as basis elements to divide into tetrahedron. Its principle is to divide the cube into five elements tetrahedric. Simplification to wish is to eliminate four tetrahedral surrounding the cubic element and to leave only the central tetrahedral. Here!
, we have archived a factor of 4 in memory reduction and 7-11 in CPU speedup over the typical meshing. Numerical results presented in this paper for a partially loaded waveguide problem, will have a great importance to valid the usefulness of this new approach.
