The frequency dependence of reflection factor of a plane electromagnetic wave that is normally impacted upon a two-element screen, have been studied. Wide and narrow walls of rectangular waveguide channels are mutually parallel. The high-Q resonances of total passage and reflection which are similar to “cutoff mode” resonances have uncovered. It is shown that the change in geometrical dimensions of the screen prowids a possibility to obtain the resonances at quite definite frequencies. %8 1006-02-03
