In the ADCOM meeting of March, 1989, the ACES Journal and Newsletter was separated into two publications - the ACES Journal, to contain peer reviewed papers devoted to applications, and the ACES Newsletter, to present informal communications, news items, and administration matters. In one year - March 1988 to March 1989 - ACES membership had grown from 300 to more than 500. The membership fee for individuals rose to $25 in 1989.
At the Fifth Annual Review of Progress, held March 20-24, 1989 in Monterey and Chaired by Michael Thorburn, 200 persons attended and presented 70 papers in 12 sessions, and 21 papers in a poster session. No parallel sessions were necessary. This was the first Review to feature short courses{three on March 20. The Review Proceedings spanned 865 pages. The ADCOM formally adopted a 2-year budget for the first time, and ACES held its first Annual Awards Banquet. The following awards were presented: the Mainstay Award to Richard Adler, Publications and Promotions Award to Robert Bevensee, Technical Achievement Award to Gerald Burke, Founders Award to Edmund Miller, Publications and Promotions Award to David Stein, and Valued Services Award to Michael Thorburn.
The first ACES Newsletter to appear after separation from the Journal >was Vol. IV, No. 1, published June, 1989. It announced the establishment of the ACES European Committee for a period of at least one year, with Rüdiger Anders (Applied Electromagnetic Engineering, West Germany) as chairman and seven founding members, who had attended the Annual Review in March. The Committee would begin the work of establishing a formal European Chapter of ACES, serving as an \ACES Europe" Committee.
Treasurer Breakall reported total income for calendar year 1988 was $57,300; total expenses, $38,000. These compared with 1987 figures of $26,715 and $9,800, respectively. As of March 24, 1989, the estimated income for 1989 was $52,750; estimated expenses, $44,300. David Stein, Chairman of the Publications Committee, reported the decision to eliminate page charges for most papers. However, excessive length papers would incur special charges to cover the extra expense. 1989 saw the publication of the first special issue of the ACES Journal, on Electromagnetics Computer Code Validation. Stanley Kubina and David Stein were the guest editors. It featured 11 articles, with an excellent lead article entitled "Characterization , Comparison and Validation of Electromagnetic Modeling Software", by Edmund Miller (then at General Research Corporation). The ACES Newsletter of June 1989, announced a call for papers for the second special issue of the ACES Journal, devoted to Canonical Problems in Computational Electromagnetics, with Harold Sabbagh (Sabbagh Associates) as guest editor. The updated computer program NEEDS 2.0 became available, but to ACES members only, at a cost of $140 ($165 for members abroad). The ACES Software Library at this time listed 16 programs. Vol. IV.2 of the ACES Newsletter, September 1989, announced Paul Elliot (then at Georgia Tech Research Institute) as the new Newsletter editor, a non-voting position on ADCOM. Raymond Luebbers (Penn State University) replaced Robert Noel as Chairman of the Meetings Committee, which was then planning ACES Workshops to start in the fall of 1990.
Richard Adler and James Logan were installing, at this time, a new desktop publishing system, permitting more timely Newsletter deliveries.
Rüdiger Anders as Chairman of the European Committee announced plans for a First European Workshop for November 1989, in the Ulm-Stuttgart area. This would be a two-day event, with a handful of invited papers and time for the participants to share their application experiences. "Hands-on" computers from Hewlett Packard GMBH, Germany, along with major electromagnetic codes and software packages, would be provided. At the IEEE APS (Antennas and Propagation Society) International Symposium and URSI Radio Science Meeting in San Jose, June, 1989, ACES participated with the Computer Applications in ElectroMagnetic Education (CAEME) Committee, chaired by Magdy Iskander (University of Utah) in a CAEME Workshop. ACES also held a Software Validation Workshop, attended by about 40 persons who formed five working groups to discuss various aspects of code validation.
The ACES ADCOM voted at its July 1989 meeting to support sponsorship of CAEME. President Logan represented ACES as a non-voting guest at the first meeting of the CAEME Policy Board in December 1989. He requested ACES membership, which would allow voting status on the Policy Board, in return for a $3,000 annual fee. Membership privileges would include access to CAEME reports and developed hardware. President Logan nominated Edmund Miller to represent ACES on the CAEME Technical Advisory Committee. In ACES Newsletter Vol. IV.3, December 1989, Wayne Harader (Ball Communications), ad hoc Chairman of the Artificial Intelligence and Expert Systems Committee, solicited inputs for applying knowledge in these areas to electromagnetic modeling.
