Ayax D. Ramirez joined SPAWAR Systems Center, Diego in 1997. He received his M.S. and B.S. in Physics from San Diego State University in 1991 and 1984, respectively. Since 1984, he has performed research and development in the areas of laser physics, photonics, micro-sensors, excimer laser materials processing, and, more recently, in nondestructive detection techniques in high-power microwave tubes. Prior to working at SSC-SD, he worked in industry as a researcher for Science Applications International Corporation (SAIC). He holds numerous patents and technical publications in his field. He is a member of the American Physical Society and an adjunct professor at Southwestern College and Grossmont

Stephen D. Russell, Head of the Advanced Technology Branch at SPAWAR Systems Center, received his Ph.D. and M.S. in Physics from The University of Michigan in 1986 and 1981, respectively. He received his B.S. in Physics and Earth & Space Science from the State University of New York at Stony Brook in 1979. He has worked at SPAWAR Systems Center (and its predecessor organizations) since 1986 performing research and development in the fields of micro-sensors, photonic devices and systems, microelectronics, excimer laser processing, novel materials, and display technologies. Prior to joining SPAWAR Systems Center, he worked as a research assistant at The University of Michigan (1979–1986) and at Brookhaven National Laboratory (1977–1978). He has published numerous technical articles and has more than 60 U.S. and foreign patents issued or pending. He is a member of the American Physical Society and Optical Society of America and also serves as a consultant and technology agent for the Missile Defense Agency (MDA) and Defense Advanced Research Projects Agency (DARPA). He is a 2001 recipient of the Federal Laboratory Consortium Award for Excellence in Technology Transfer and holds two NASA Space Act Awards. He can be reached at

David W. Brock, a Scientist in the Antennas and RF Technology Branch at SPAWAR Systems Center, received his Ph.D. in Physics from the University of Texas at Austin in 1981 and his M.S. in Physics from the University of Colorado at Boulder in 1975. He received B.S. degree in Physics and Mathematics at the New Mexico Institute of Mining and Technology in 1972. Prior to joining SPAWAR Systems Center, Dr. Brock worked as a research assistant at the University of Texas (1977– 1981) and the University of Colorado (1975). He has worked at SPAWAR Systems Center since 1981 initially in the High Power Microwave Tube Branch and later in the Microwave/Millimeter Wave Technology Branch. He has carried out research work in areas including high power microwave tubes, the design and building of radar systems, microwave receivers, and antennas. He has published several technical articles, and has seventeen patents issued or pending. Dr. Brock can be reached

Narayan R. Joshi, faculty at the Welding Technology Department of North Harris College, received his M.Sc. in Electronics from Poona University, India. He received his M.S. and Ph.D. in Mechanics and Materials Science from Johns Hopkins University. He has worked as the Head of the dual Engineering Degree at the University of Maryland, Baltimore; Lamar University; and Prairie View A&M University. His academic teachings include elastic wave propagation, Materials Science, Metallurgy, Mechanical Vibrations, and Advanced Non-Destructive Evaluation Methods. His experimental research includes Ultrasonics, Acoustic Emission, X-ray diffraction and Optical Materials (Lasers without Inversion). Mr. Joshi has worked for General Electric, Oak Ridge National Laboratories, Southwest Research Institute, and Texas Instruments. He has about 55 research
