Annotation: In this article we present the results of numerical investigation of complex propagation constants in circular twolayer waveguides. It is shown that in the off-limit frequency range the waveguides has new properties. On the basis of these properties of the transducers for the measuring of permeability different materials can be developed.

Keywords: permeability, evanescent two-layer circular waveguide, propagation constant
