Washington, D.C. 20418 at $2.00 for meetings prior to 1970, $3.00 for 1971 - 1975 meetings, and $5.00 for the 1976 meeting, and $6.00 for the 1977 meeting. The full papers are not published in any collected format, and requests for them should be addressed to the authors who may have them published on their own initiative. Please note that these meetings are national and are not organized by international URSI, nor are these programs available for the international Secretariat. WELCOME TO SAN FRANCISCO The steering connnittee of the 1977 APS-URSI Symposium welcomes you to San Francisco and the campus of Stanford University, The Technical Program Connnittee headed by Professor Kenneth K. Mei has worked tirelessly to provide you with an outstanding collection of papers describing the latest advances in the field of electromagnetics. We hope that you will find your visit here professionally stimulating and rewarding. San Francisco is the cultural and financial center of the western United States. It abounds in museums, art galleries, opera, ballet, theatre, restaurants, sports and entertainment of all kinds. We hope that you will find the time to sample and savor this galaxy of attractions. To this end, Dr. Tony Jennetti, Chairman of the Arrangements Connnittee, has planned two special events for you. California is the wine capital of the United States. On Tuesday evening we will visit the famous Paul Masson Winery to taste their wines and enjoy an outdoor steak barbecue dinner. San Francisco boasts the largest Chinese settlement in the United States. On Wednesday evening we will travel to romantic and enchanting Chinatown for a magnificent Chinese banquet at the Four Seas Restaurant. Finally, I wish to thank all those who helped to make this Symposium the grand event that it is: the connnitteemen, the speakers, the session chairmen, Stanford University and our Industry supporters. We are all volunteers. No one is paid for his services. If you find the opportunity, take a minute to thank these hard working members personally for.their efforts, For without them, there would be no Symposium.

Jeff Lytle IN MEMORY OF Professor Samuel Silver, born in Philadelphia, Pennsylvania(USA) on February 25, 1915, died on November 5, 1976, in Walnut Creek near Berkeley, California (USA). He is survived by his wife, Marjorie Silver, a son Daniel Silver, a daughter Deborah Brewer, both of Maryland (USA), and six grand-children. Professor Silver's affiliation with URSI began after World War II when, in 1950, he became a member of the USA National Committee. He served as Chairman of USA Commission 6 from 1950-1954 and thereafter as Secretary (1957-1963) and Vice-Chairman (1963-1966) of the USA National Committee. At the same time, he held positions within the URSI International Organization: Chairman of Commission 6 (1952-1957), Vice President (1963-1966) and President (1966-1969). He also was Chairman of the Committee on Space Radio Relays and Committee on Space Research (C0SPAR)(l957-l966), and URS!. representative to the Executive Councils of COSPAR and ICSU (International Council of Scientific Unions). He was a delegate to every General Assembly of URSI since 1950, and was elected permanent Honorary President of URSI at the Warsaw General Assembly in 1973. While his broad scientific interests related to the work of several of the URSI Commissions, Professor Silver's closest contacts remained with Commission 6. He was a major participant in the conception and organization of the first International Electromagnetic Wave Theory Symposium at McGill University, Montreal, Canada, in 1953.
