Wireless communication networks of desert-belt nations can be severely compromised by frequent dust/sand (DUSA) storms. Existing attenuation and scattering models for electromagnetic (EM) waves often consider homogeneous DUSA media. This article proposes an analytical model of a layer-based DUSA storm to monitor the EM attenuation from different DUSA layers. A lab-based experimental setup is used to measure the attenuation from a specific DUSA layer. The measured results are used to validate an equivalent professional simulator [high-frequency structure simulator (HFSS)] model of the DUSA layer. The agreement between the proposed analytical and simulated results demonstrates the redundancy of complicated experimental validation process. The simulation model also allowed the monitoring of EM attenuation due to different particle sizes, shapes, and concentrations in different homogeneous layers of the DUSA storm. The predicted EM attenuations agreed well with the data available in the literature.

层状 DUSA 风暴引起的微波辐射非均匀散射：理论与实验

沙漠地带国家的无线通信网络可能会受到频繁的沙尘暴 (DUSA) 的严重影响。现有的电磁 (EM) 波衰减和散射模型通常考虑均匀的 DUSA 介质。本文提出了一个基于层的 DUSA 风暴的分析模型，以监测来自不同 DUSA 层的 EM 衰减。基于实验室的实验装置用于测量特定 DUSA 层的衰减。测量结果用于验证 DUSA 层的等效专业模拟器 [高频结构模拟器 (HFSS)] 模型。所提出的分析和模拟结果之间的一致性证明了复杂的实验验证过程的冗余。仿真模型还允许监测由于不同颗粒大小、形状、DUSA 风暴的不同均匀层中的浓度和浓度。预测的 EM 衰减与文献中可用的数据非常吻合。
