Article Type: Preface From: COMPEL: The International Journal for Computation and Mathematics in Electrical and Electronic Engineering, Volume 28, Issue 3

It is a great pleasure to introduce the special issue of COMPEL: The international journal for computation and mathematics in electrical and electronic engineering (COMPEL) with selected papers presented at the 20th Symposium on Electromagnetic Phenomena in Nonlinear Circuits (EPNC’08) held in June 2008 in Lille, France. The 20th EPNC Symposium was organized by University of Lille – Laboratoire d’Electrotechnique et d’Electronique de Puissance, University of Liege – Department of Electrical Engineering and Computer Science, Electrical Engineers Association of the Montefiore Institute – Belgium, and Polish Society for Theoretical and Applied Electrical Engineering – Poznan Section. Professor P. Dular from University of Liege and Professor F. Piriou from University of Lille were the Chairmen of Organizing Committee and Local Organizing Committee.

The first Symposium on Electromagnetic Phenomena in Nonlinear Circuits took place in Poznan, Poland in November of 1972. The first 11 conferences were local events. Nevertheless, speakers from other countries also took part. The last nine conferences were international with proceedings published in English. At first, the selected papers of EPNC were introduced into the regular issues of COMPEL. After EPNC in 2004 in Poznan, first time, the selected papers of EPNC were published as a special issue of COMPEL journal. Current issue of COMPEL is the third special issue with EPNC papers.

The aim of the EPNC’08 was to present the recent advances in the analysis and synthesis of nonlinear electric and magnetic circuits and nonlinear optics as well as to provide the forum for discussion on applications of nonlinear phenomena in electrical engineering. The EPNC conferences are intended to be opportunity to exchange ideas and experience for specialists in electromagnetic field modelling, electric drives, electronic, electrical machines, electric and magnetic materials. Topics of the EPNC’08 Symposium in Lille included:

1. 1.

   Ferromagnetics and magnetic circuits:

   • •

     theory and application of nonlinear phenomena in ferromagnetic elements and structures containing such elements;

   • •

     electromagnetic field calculations in nonlinear problems; and

   • •

     modelling of material properties and the numerical treatment of hysteresis, anisotropy, permanent magnets.

2. 2.

   Semiconductors and nonlinear electric circuits:

   • •

     electric circuits with nonlinear elements;

   • •

     modelling and control of power electronic devices and converters; and

   • •

     modelling and simulation of nonlinear electronic elements and systems with such elements.

3. 3.

   Nonlinear optics and wave propagation:

   • •

     nonlinear optical phenomena and devices;

   • •

     modelling of nonlinear space-time electrodynamics; and

   • •

     modelling of nonlinearities in optical waveguides.

At the EPNC in Lille, more than 70 papers were presented by participants coming from 15 countries. Two page versions of all papers were published in EPNC’08 Proceedings. A limited number of 22 papers in extended version were selected by EPNC’08 Editorial Board and COMPEL Guest Editors for publication in this special issue of COMPEL journal.

We hope that this issue of COMPEL will provide various interesting new information to the readers.
