Unstructured PEEC formulation by dual discretization

This letter presents a new lumped parameter approach for the solution of the electromagnetic problem of a system of conductors lying in a homogeneous region. By exploiting duality relations between two systems of meshes, an equivalent network of lumped parameters is obtained. This approach is conceptually equivalent to the partial element equivalent circuit formulation but it can overcome the limits imposed by a regular discretization present in its original version. Details about computation of lumped parameters and definition of equivalent network are given. Results obtained on two configurations referenced in the literature are finally discussed
