On Application of Parabolic Equation Method to Propagation Modeling in Millimeter-Wave Bands

Abstract

This research studies the millimeter-wave (mmWave) propagation mechanisms and corresponding numerical methods. 5G mobile communication systems are expected to operate in mmWave bands, thus the development of the mmWave propagation models is vital for the wireless communication study. In contrast to most other publications, this research is based on the electromagnetic theory and rigorous differential equations. Diffraction, scattering, refraction and attenuation of the radio waves can be computed and visualized. Arbitrary terrain profiles and weather conditions can be accounted. The widely used parabolic equation (PE) framework is applied. State-of-the-art PE based numerical methods are considered with a focus on the mmWave propagation. Numerical examples under various propagation conditions are given.
