Calculation of Mutual Inductance Between Circular and Arbitrary Shaped Filaments: Segmentation Method

A new semi-analytical formulation for calculating the mutual inductance between a primary circular filament and a secondary filament positioned arbitrarily in space is presented. The method flexibility allows the secondary filament to take any random shape. It also has a very simple kernel as compared to its predecessors. The accuracy of the presented method has been successfully validated against results from similar models, and also against FastHenry software. Furthermore, the formula can be used to model complex electromagnetic systems and predict their performance.
