Analysis on Propagation Characteristics of Highway Communication Using Hybrid FDTD and Ray-Tracing Method

The propagation characteristic of highway communication is investigated by using FDTD/ray-tracing method numerically. To achieve the accurate radiation characteristics, much tinier mesh size of FDTD and ray-tracing method are employed. Take the complicated environment in the inter-city highway into consideration, tunnel with leaky coaxial cable, antenna and sensors are included to realize the propagation characteristic of the system. The experimental and numerical results show that the radiation field of the mobile inter-city highway communication system can be obtained efficiently and exactly.
