A fork waveguide model is proposed and the mode matching and multi-mode network technique are used to analyze the transmission characteristics of rectangular tunnel with metallic pit prop.
The prior wafer transmission device fails to adjust a wafer fork horizontal when the wafer fork is inclined, which results in breakage when the wafer handle collides the wafer.
