โœฆ Synopsis

A one-dimensional exterior electromagnetic scattering problem is formulated using a differential equation approach followed by a finite element discretization. By interpreting the resulting linear algebraic equations as node voltage equations for a transmission line, a boundary element is obtained which satisfies the requirement of no wave reflection at the edge of the finite element region. Numerical results which show the elimination of non-physical standing waves from the scattered field are presented and discussed.

In this paper, a new element for higher order rod (normally referred to as Minlin-Herrman rod) is formulated by introducing lateral contraction e ects. The cross-section is assumed to be rectangular. The sti ness and mass matrices are obtained by using interpolating functions that are exact solution
