Application of multi-resolution terrain in electromagnetic wave propagation research

This paper proposes a kind of multi-resolution terrain which can be used in simulation of electromagnetic wave propagation in complex terrain. Using this kind of terrain can accelerate simulation in a large scale while keeping a high-accuracy result. It can be used as the terrain model when simulating electromagnetic wave propagation. In this paper, the author constructs a multi-resolution terrain which is transformed from a digital elevation model and makes some analysis of the simulation result.
