A modified PEEC model was introduced, in which the integral definition of vector magnetic potential and the Lorentz gauge are used to expand the integral equation to derive the PEEC. This avoids using the integral definition of the scalar electric potential and consequently avoids the capacitance matrix extraction in complex dielectric structures, which can save a large part of computing time. This model presents the modified nodal approach(MNA) equations instead of the equivalent circuit of the structure. So that it is suitable and convenient for hierarchical electromagnetic modeling. The numerical results show the validity of the presented model.
