“…A hybrid simulation method involving FDTD and raytracing was proposed to simulate the indoor propagation of incoming waves [26]. Authors have proposed the hybrid method of FEM and ray-tracing methods suitable for airport surface [27]. There are dense built-up areas, such as passenger terminals and control towers near the runway.…”

In this paper, a hybrid electromagnetic simulation method of two-dimensional FDTD and ray-tracing methods suitable for an airport surface was proposed. The power variation due to ground reflection, refraction and creeping is calculated by two-dimensional FDTD method and ray-tracing method is used to calculate the reflecting and diffracted powers from buildings. The proposed approach was validated by measurement using a 1/50 scale-model of an airport model with a building model in various positions at 5 GHz. The proposed method allowed measured power distributions to correlate with simulated figures to within 4.8 dB and their null positions were also estimated to an error tolerance of within 0.01 m.
