Abstract :
This paper presents a ray-tube tracing method for wave propagations in curved tunnels. The waves from a transmitting antenna are modeled with many ray tubes, and those ray tubes are traced by including multiple reflections and diffractions from curved structures. Measurements for signals in curved road tunnels from GSM900/1800 base stations have been performed and are compared with those obtained from the ray-tube tracing method.
