Distinguished Professor EmeritusElectrical & Computer Engineering Education 1970 Ph.D. Electrical Engineering, California Inst. of Technology 1967 M.S. Electrical Engineering, California Inst. of Technology 1966 B. Tech Electrical Engineering, Indian Inst. of Technology, Kanpur, India Biography Dr. Singh has nearly 30 years of experience in numerical modeling and simulation of electromagnetic and plasma systems. He has richly contributed to the field of space plasma research through particle simulation of complex plasma processes such as antennas in plasmas, formation of electric double layers, waves and instabilities, large-scale plasma flow and charging of spacecrafts. His most recent works have been on development of a 3-D plasma codes for satellite-plasma interactions in NASA’s tether project, and nonlinear evolution of waves in space plasmas; the codes employ the particle-in-cell method. The 3-D code was recently parallelized. Dr. Singh has recently developed a code for studying dynamical behavior of photorefractive materials used in nonlinear optics. He has also developed 1- and 2-D particle-in-cell codes for liquid crystal devices having widespread applications in displays.
