摘要：
We consider a resonant cavity in the form of a section of a weakly irregular metal tube coupled with a waveguide of larger cross section. Eigenmodes of such a cavity with frequencies close to the cutoff frequency are described by the inhomogeneous-string equation. The solution of this equation obtained by the variational technique leads to standard formulas for interaction between the cavity and an incident wave.
