Abstract

The existence of metallic pit prop causes the discontinuity of rectangular tunnel. A fork waveguide model is proposed for the transmission characteristics analysis. Mode matching and multi-mode network technique are used to analyze the transmission characteristics for rectangular tunnel with metallic pit prop. Moreover, the relationship between the reflection coefficient of dominant mode TE₁₀ and working frequency and the row number of metallic pit prop are obtained, respectively. The present approach can be used to analyze other discontinuity problems caused by metallic obstacle in rectangular tunnel.
