A REVIEW OF FINITE-ELEMENT OPEN BOUNDARY TECHNIQUES FOR STATIC AND QUASI-STATIC ELECTROMAGNETIC-FIELD PROBLEMS

This paper presents a review of finite element open boundary technique s for the computation of static and quasi-static electromagnetic field s. The underlying assumptions and ideas behind these techniques are ou tlined and explained, The advantages and shortcomings of each techniqu e are discussed. The goal of this review is to aid those working on nu merical solutions of open boundary problems using the finite element m ethod to gain perspectives on the variety of techniques presently avai lable or being developed. This review is also intended to facilitate t he communication of numerical techniques between the low-frequency fie ld computation community and those in the high-frequency community.
