摘要：
The cutoff characteristic equation of the modes in circular waveguide is derived in this paper. The TM01 mode inversion has been investigated. Two kinds of technique of dielectric loading have been discussed. When the dielectric tube is filled in the waveguide next to the waveguide wall, there is no window of TM01 mode inversion observed in the cutoff characteristics. Contrarily, when the dielectric is filled centrally in the circular waveguide, there always exists one "window", within which the TM01 mode can propagate in the waveguide in the sense of single mode.
