摘要：

In this paper we provide a modified 3D Uniform Theory of Diffraction (UTD) model for afinite-length cylinder, and validate the model by comparing to the simulation and the measured data. The presented finite-cylinder UTD model is adapted from the conventional infinite-cylinder model, and we additionally add edge diffraction occurring at the edge of the cap of the finite cylinder. The simulation reference is obtained from the CST simulation and the measurement reference is obtained from a vector network analyzer based channel sounder. From the numerical examples and analysis, it is shown that the modified model agrees well with the references and is more accurate than the conventional unmodified model. This study proves the importance of the edge diffraction field for finite-cylinder UTD solutions specially when 1) the transmitter and receiver are at different heights relative to the cylinder, and 2) one is below and the other is above the height of the cylinder.
