| Summary: | Determining the Particle Size Distribution (PSD) of a solid and liquid particles is of great practical interest. An experimental research was conducted to explore the influence of PSD on propagation properties of electromagnetic wave specifically in microwave and millimeter wave bands. The majority of earlier studies have primarily concentrated on the homogeneous spherical dust particles in mathematical models and equations. Besides, the lack of information on particle shape is one of the main causes for inaccurate calculation and extrapolation. Dust grain is of random shape nevertheless it is analogical to the ellipsoid in the real environment of dust media in collected works. In this paper, emphasis on the shape of particle at Sand and Dust Storm (SDS) phenomena in the microwave and millimeter wave with the actual physical measurement is presented and discussed. Moreover, the examined samples used in the demonstration is the dust grains taken from the Central North of Sudan. The findings of the experiment are essential to many aspects; namely size, shape, number of particles, and A three dimensional relationship is then displayed for these dust particular size with particle diameters (μm), normalized particle amount (diff), and samples code number. Contribution of this study is that specific particle shape distribution with all the parameters could be assist in determine of charge, volume fraction, visibility, and concentration at SDS. This is also useful in many new applications and services such as image radar, remote sensing, and telecommunications links. |
