Electromagnetic Wave Radiation, Scattering, and Propagation Analyses and Visualization
Recently, urban propagation environment of electromagnetic wave has become complicated. For high-frequency wireless communication bands, such as UHF, the propagation characteristics depend largely upon the local feature of the surrounding scatterers, and high-frequency asymptotic ray treatment could be a great tool for estimating the field strength. In this presentation, adaptive Shooting and Bouncing Rays (SBR) method has been used to predict the field strength map and path loss evaluation in rather irregular geometries bounded by surrounding buildings and mobile vehicles. Finite Difference Time Domain (FDTD) method has also been used to estimate the scattering field in more complicated configurations such as a human body. Efforts have been made to present the computed results in three-dimensional space for understanding the wave propagation and scattering mechanism easily. Several examples showing radiation and scattering field distribution will be given in the presentation.

Biography: Hiroshi received the B.S. and M.S. degrees in Electrical Engineering from Shizuoka University, Japan, in 1980 and 1982, respectively, and the Ph.D. degree from Polytechnic University, New York in 1986. He was a Research Fellow, then a Postdoctoral Scientist until March 1987 in Polytechnic University. Since April 1987, he has been with Chuo University, Tokyo, Japan, where he is currently a Professor and an Associate Dean of Faculty of Science and Engineering. He received the R.W.P. King Best Paper Award from the Antennas and Propagation Society of IEEE in 1987. His current research interests include wave propagation and diffraction in time harmonic and transient domains.
