Abstract

The finite element method (FEM) solving of electromagnetic field problems in unbounded domains generally represents a very onerous task and requires specialized techniques such as ballooning, infinite elements, hybrid FEM/BEM and use of transformations’. In the last few years the authors have successfully developed an iterative procedure to cope with unbounded electrical field problems2. The main advantage of the procedure lies in its simplicity of implementation in a standard FE code for bounded problems and in its robustness.
