Study on cut-off frequency of abnormity wave-guide

SUN Jiping,ZHANG Changsen(InfoResearch Institute, Beijing Campus, China University of Mining and Technology,Beijing100083, China)  
The changing characteristic of cutoff frequency in abnormity waveguide that is formed from the basic shape of trapezium, semicircle arch, rectangle and hexagon is studied by using finite element method in this paper A conclusion is drawn out that cutoff frequency will decrease linearly with the increasing of crosssection girth of waveguide and using leasttwomultiplication method we also draw out the similar changing curve between them The result has an important reference meaning to wireless communication in finite space of railwaytunnel, mine well tunnel
