The main research activity in this area has been and are performed, by [[Albert E. Ruehli|Albert Ruehli]]<ref>A. E. Ruehli: Equivalent Circuit Models for Three-Dimensional Multiconductor Systems, IEEE Transactions on Microwave Theory and Techniques, Vol. 22 (1974), Nr. 3</ref> at [[IBM Thomas J. Watson Research Center]], starting with a publication in 1972. At that time the foundation of the PEEC method was presented, i.e. the calculation of the partial inductances. The PEEC method was extended to more generalized problems, including dielectric material and retardation effect.

The PEEC method is not one of the most common techniques used in EM simulation software or as a research area but it has just been starting to gain recognition and for the first time there is a session at the 2001 [[IEEE]] EMC Symposium named after the technique. In the mid -1990s, two researchers from the [[University of L'Aquila]] in Italy, Professor Antonio Orlandi and Professor Giulio Antonini, published their first PEEC paper and are now together with Dr. Ruehli considered the top researchers in the area. Starting year 2006, several research projects have been initiated by the faculty of Computer Science and Electrical Engineering of [[Luleå University of Technology]] in Sweden in the focus area of PEEC with the emphasis on computer-based solvers for PEEC.

Line 57 ⟶ 56:

Model Order Reduction (MOR) has become an active research topic for circuit models in general and PEEC models in particular. Integration of a PEEC model directly into a circuit simulator is computationally expensive for two main facts. One is that a large number of circuit elements are generated for complex structures at high frequencies, and the other is that the circuit matrices based on modified nodal analysis (MNA) are usually dense due to full inductive and capacitive coupling. In order to model/simulate such problems efficiently, developing compact model representation via model order reduction is desirable for PEEC modeling.
