'''Partial element equivalent circuit method (PEEC)''' is partial [[inductance]] calculation used for interconnect problems from early 1970s which is used for numerical modeling of [[Electromagnetism|electromagnetic]] (EM) properties. The transition from a design tool to the full wave method involves the [[capacitance]] representation, the inclusion of time retardation and the dielectric formulation.

===PEEC model reduction===

The rigorous full-wave version of the PEEC method is called (Lp,P,R,t) PEEC, where Lp is partial inductance, P is potential coefficient (inverse of capacitance), R is resistance, and t is delay. If available, reduced model of the full-wave version can be used. For example, if the EIP structure is electrically small, the delay term t can be omitted and the model can be reduced to (Lp,P,R) PEEC model. In addition, if frequency is sufficiently high so that w*Lp >> R, we can omit R term and use approximate (Lp,P) PEEC model. According to various modeling situations, (Lp) and (Lp,R) models are also useful.
