FREEMAN and WILLIAM L. WILSON Rice University Houston, Texas Abstract — This constitutes the full report of the SPS Microwave Power Transmission System review panel. 1. INTRODUCTION The Satellite Power System (SPS) Workshop on the Microwave Power Transmission System (MPTS) was held at the Johnson Space Center in Houston, Texas on January 15-18, 1980. The objectives of this workshop were to assess and critique the assumptions, methodologies and conclusions of the NASA SPS studies and to identify and assess critical issues and to make recommendations for follow-up work. The workshop review panel consisted of individuals with expertise and experience in each of the areas relevant to the MPTS. Dr. Robert C. Hansen, of R. C. Hansen Inc., and Professor Bernard D. Steinberg of the University of Pennsylvania both provided expertise in the area of microwave beam shaping and phase control. Professor Aldo V. da Rosa of the Stanford University Radioscience Lab was the expert on microwave-ionosphere interactions. Mr. Harry Goldie of Westinghouse and Dr. Paul Tallerico of the Los Alamos Scientific Laboratory contributed in the area of high power microwave tubes. Professor William L. Wilson, Jr. of Rice University provided expertise in the area of solid-state microwave devices and waveguides. Dr. John W. Freeman, Rice University Professor of Space Physics and Astronomy, and chairman of the workshop, represented a broad knowledge of the SPS concept and its historical development and microwave energy conversion devices. The format of the workshop consisted of presentations by NASA and contractor personnel in each of the following areas: system performance; phase control; power amplifiers; radiating elements; rectenna design; solid state devices; and planned program activities. These presentations were arranged by Mr. R. H. Dietz of JSC. A large amount of material was presented. Following each day’s presentation, the review panel met privately and discussed the material that was presented. They also met for the entire afternoon of the last day to discuss their conclusions. Administrative arrangements were made by Texas A&M University under the direction of Dr. Richard Thomas.
