Abstract

Abstract

To achieve an accurate characterization and thorough understanding of the millimeter-Wave (mmWave) communication channel propagation mechanism, precise characterization of diffuse scattering propagation and polarization is crucial. These aspects are also indispensable for the development of a high-precision mmWave channel model. In response to the insufficient characterization of diffuse scattering propagation and polarization caused by building materials in the mmWave frequency bands, a novel diffuse scattering depolarization modeling method based on effective roughness theory is presented in this paper. Initially, the electric field of the diffuse scattering radiation produced by the rough surface of building materials is decomposed along the polarization dimension of the electromagnetic wave. Subsequently, the depolarization coefficient is introduced to establish the propagation model. The paper investigates the diffuse scattering propagation and polarization characteristics, encompassing the power angle spectrum, depolarization coefficient, and cross-polarization discrimination ratio, by utilizing measured data of typical materials in the 40～50 GHz frequency range. The obtained results validate that the proposed model effectively captures the polarization characteristics of building materials with both rough and smooth surfaces. The achieved depolarization conversion rates are 39% and 4%, respectively.
