...S. Alfonzetti; G. Borzì; N. Salerno This paper discusses the perfectly matched layer method recently proposed for the computation of static or quasistatic fields in open boundaries. In particular it is shown how the method can be derived by means of a particular co‐ordinate transformation applied...

...Stanislaw Gratkowski The paper presents infinite elements for axisymmetric electrical field problems with open boundaries. The formulation of the elements is so simple that closed‐form expressions for the infinite element matrix are obtained. In order to test the infinite elements, a simple problem...
