Resonant properties of semi-infinite place and rectangular waveguides in the presence
of a thin conductive diaphragm placed near the cross-wall are investigated. The diffraction problems
of electromagnetic waves by diaphragms are reduced by the method of integral-series identities to
the infinite sets of linear algebraic equations. It is found that at some values of the frequency of the
excitatory wave there is a sharp resonant increase of the amplitude of standing waves in the area
between the diaphragm and the flange.
