Findings of mathematical simulation and experimental research of frequency response of bandpass filters on the basis of two metal surfaces with repetitive cross recesses and dielectric filling between them depending on dielectic properties of the filling were described. Influence of dispersion of dielectric permittivity onto filter band was shown.
