Annual membership dues were increased $10, effective April 1, 1991. The new rates became: individual, $45 (U.S.) and $55 (non U.S.); institutional, $95 and $195; student, $25. The budget for 1990 posted a net worth (assets minus liabilities) on December 31 of $34,326. Income was $71,883; expenses, $68,607.

The second ACES-TEAM Workshop was held in Sendai, Japan, following the International Seminar on Computational Applied Electromagnetics, January 31-February 1, 1991. It was hosted jointly by the Electrical Engineering Department of Hokkaido University and the Institute of Fluid Science of Tohoku University. The third Workshop was scheduled for Sorrento, Italy, following the COMPUMAG meeting held July 7-11. These workshops focussed on the use of canonical problems to validate electromagnetic codes and models.

The Seventh Annual Review of Progress, held March 18-22, 1991 and chaired by Frank Walker, featured a number of new highlights: a Featured Canonical Problems Review, CAEME special session, 14 vendor booths, six short courses, and a video tape of an MIT tutorial, presented by CAEME. This tutorial was entitled "Fundamental Demonstrations of Electromagnetic Fields and Energy", by M. Zahn, J.R. Melcher, and M.L. Silva. Eighty-one papers were presented in 17 sessions. In an international forum ACES regional representatives from 8 regions - Great Britain, Western Europe, Eastern Europe, Australia, Japan, China, South America and South Africa - reported on topics of technical importance to each region. The Proceedings of this Review spanned 703 papers. In 1991 Boeing Co. made a grant to ACES which allowed a representative of the Polytechnic Institute of Bucharest, Romania, to attend the Annual Review. In 1992 a repeat grant would allow a representative from Jiaotong University in Xi'an, Peoples Republic of China, to attend that Review.

James Logan and Edmund Miller were reelected to the BOD and Andrew Peterson became a new Director. Karl Kunz (Penn State University) replaced James Logan on the CAEME Board. Andrew Terzuoli (Air Force Institute of Technology) and Frank Walker replaced Charles Vandament as co-chairmen of the Software Exchange Committee. Russell Taylor (McDonnell Douglas Helicopter Co.) replaced Christopher Smith as Chairman of the Code Users Group. Membership in ACES now stood at 510: 398 in the U.S.; 19 in the rest of North and South America; 63 in Europe, 5 in Asian and African countries; and 25 in the Pacific Rim.

John W. Williams (Science Applications International Corporation, SAIC) and Managing Editor Adler had arranged for the inclusion of the ACES Journal in various international abstracts and indexing databases. A Call for Papers was announced for a Journal special issue on Computer Applications in Electromagnetics Education, with Magny Iskander as special guest editor. The BOD met June 25 at the 1991 International APS and URSI Symposium, held at the University of Western Ontario. It elected the following officers for the next 2-year term beginning in March of 1992:

President, Harold Sabbagh

Vice President, Raymond Luebbers

Secretary, Richard Adler

Treasurer, James Breakall

The Board also approved the establishment of an ACES United Kingdom Chapter after the foundation work performed by Anthony K. Brown (EASAT Antennas Limited) and Patricia Foster (Microwave and Antenna Systems), of the UK NEC Users Group. Patricia Foster would also chair the Eighth Annual Review in Monterey, March 1992.

Vol. VI.3 of the Newsletter, November 1991, announced an ACES Workshop on "Applied Computational Electromagnetics Directions for the Nineties" in Melbourne, Australia, on August 14, 1992. Anthony H. J. Fleming, the ACES International Workshop Chairman, was the organizer. It was sponsored by ACES, the Telecom Australian Research Labs, The Victoria Section of the IEEE, the Defence Science and Technology Organization, and TEAM. A special Journal issue was announced : "Bioelectromagnetic Computations", with Anthony Fleming and K. H. Joyner as guest editors. Another special issue entitled \Applications of High-Frequency Methods and Computer Technologies in Electromagnetics", with Fulvio Bessi (Ingegneria dei Sistemi S.p.A.) as guest editor, was published the summer of 1991 and available for purchase. At the end of 1991 the ACES UK Chapter was formed, with these officers:

Anthony Brown, Chairman

Patricia Foster, Treasurer

David Lizius (Culham Lab, UK), Secretary.

In addition, three other members belonged to the founding committee. At this time ACES had 525 members, with approximately 26% from non-U.S. countries. These included 8 students, 83 organizations, and 434 individuals. 12.Total membership increased during 1991 by 10% but the non-U.S. component declined 14%.
