Abstract

─ The propagation of electromagnetic waves guided in tunnels and mines is an area of scientific study which is hard to model due to multiple reflections on walls and surrounding obstacles. A novel propagation model for underground tunnels based on the weighting sum of the log-distance propagation model, the modified waveguide model and, the far zone propagation model for the ultra-high frequency (UHF) band is proposed in this paper. The propagation model is divided into five regions based on the distance between the transmitter and the receiver. Each region shows a different propagation characteristic and modeled with weighting sum of the base propagation models. Our model was tested in a tunnel with 2 m x 1.5 m cross-section and 250 m length. Measurement results are consistent with the proposed propagation model. Index Terms ─ Propagation modeling, underground tunnel, underground communications.

基于加权系数法的地下隧道信号传播建模

─电磁波在隧道和矿井中的传播是一个科学研究领域，由于在墙壁和周围障碍物上有多次反射，因此很难建立模型。本文提出了一种基于超高频(UHF)波段的长距离传播模型、修正波导模型和远区传播模型加权和的新型地下隧道传播模型。根据发射器和接收器之间的距离将传播模型划分为五个区域。每个区域表现出不同的传播特性，并用基本传播模型的加权和建模。我们的模型在一个2米× 1.5米横截面和250米长的隧道中进行了测试。测量结果与提出的传播模型一致。索引术语─传播建模、地下隧道、地下通信。

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
