Abstract

In this work an innovative method for fast analysis of geometrical variations of electromagnetic field problems is proposed. The method is based on a geometrical perturbative approach for the solution of a linear differential operator in presence of small domain modifications. The perturbative theory is general, but in this contribution has been embedded in a classical finite element (FE) framework to achieve a very fast technique for the field evaluation in synthesis or tolerance investigation of electromagnetic problems.
