It is shown that there is reflected wave in corrugated waveguide. The reflected wave is maximum near Bragg frequency and decreases symmetrically as frequency changes near Bragg frequency. The constructed filter using a corrugated waveguide is not tunable. Using several corrugated waveguides in cascade it is possible to obtain tunable bandpass filter. In this paper formulas for transmittance of two and three cascaded grating stages, separated by phase shift sections, are developed and their responses are studied.
