| Outline of Final Research Achievements |
Because of recent rapid growth of high speed mobile communication, effective base station installment and accurate electromagnetic wave propagation estimation are required. Especially for urban propagation environment with many high rise buildings, it is difficult to establish secure communication channels for wireless signals. In this research, Shooting and Bouncing Rays (SBR) method has been applied to estimate the scattering field. Special attention has been made to obtain multiple reflected, transmitted, and diffracted rays effectively to save the computational time. Then these results are visualized for better understanding of the wave propagation phenomena.
