Because of a bug in our ERM, we were able tocomplete only a portion of the environmental testing. Aslight modification to the ERM actuator will make it possibleto complete the testing should the need arise later.There are several minor mechanical modificationsthat will improve the deployment of the reflector. Usingcomposite rods for the stays with a slightly larger diametershould stretch the reflector tighter to obtain a better shape.Longer stay adapters should be used to reduce the forces onthe ends of the stays. A method of fabricating the reflectorother than sewing may provide a more accurate reflector.8. References1. L. H. Bowen, E. G. Farr, J. P. Paxton, A. J. Witzig, C. E. Baum,D. I. Lawry, and W. D.

Triennial Reports CommissionsCOMMISSION AThis triennium report was prepared by Dr. Q. Balzano,Commission A Chair 2002-<strong>2005</strong>.In the triennium 2003-<strong>2005</strong> Commission A has beenactive in support of the Scientific Committee onTelecommunications (SCT), of the Solar Power SatelliteProject and in preparing the sessions of the <strong>2005</strong> GeneralAssembly in New Delhi.In addition to session KA, session KE was giventechnical support.Specific suggestions to the STC regarded thepossibility of unexpected interference phenomena due tothe proliferation of electronic devices for communicationand health maintenance. The support for the SPS programconsisted in preparing a sufficiently detailed test programfor the large antenna of the SPS.A substantial effort was dedicated to inviting two topexperts in Ultra Wide Band (UWB) Technology to give ageneral lecture and a paper on UWB signaling at the <strong>2005</strong>GA. Profs.H. Bertoni ( N.Y. Poly), W. Stark (U.of Michigan),Broderson ( Berkley) and Milstein (USC) were contactedand invited to New Delhi. Not one of these distinguishedscientists was available.Liaisons were maintained with Commission K, byattending the meetings organized by Commission K at theBEMS Symposia of 2004 and <strong>2005</strong>.The <strong>Radio</strong> <strong>Science</strong> <strong>Bulletin</strong>Two papers are in preparation for the <strong>Radio</strong> <strong>Science</strong><strong>Bulletin</strong>:I. I. Smolyaninov, Q. Balzano, C. Davis “ A Review ofPlasmon Polariton Excitation in Doubly Periodic Arrayof Holes”II. K. Foster and Q.
