Abstrakt v dalším jazyce:	The paper proposes the possibility of metamaterial structure using for the transmission properties of open waveguide probe changing and the possibility of microwave open waveguide sensor tuning with metamaterial structure to be used for nondestructive testing of dielectric materials properties. The aim of our work was to develop a frequency selective sensor in microwave frequency band sensitive to changing of dielectric properties of investigated dielectric material. In the paper we describe the new approach with incorporation metamaterial structures with negative permittivity and permeability in the volume of waveguide sensor in order to create the stop-band properties of designed sensor. The optimal number of metamaterial units and metamaterial structures inserted into waveguide volume were numerically optimized and experimentally verified for chosen frequency band from microwave frequencies region.
