We theoretically investigate the properties of defect mode in one-dimensional lossy metamaterial photonic crystal doped with single-negative materials photonic-quantum-well (PQW). We examine the defect mode as a function of the type of negative index materials (NIMs) and the number of the unit cells of four different defected structures. The results obtained that the parameters; frequency, height, and the number defect modescan be tuned by varying the type of NIM in defect layers, PQW structure, and the unit cells as well in the defected structure. The defect modest end to show a shift in the frequency based on the particular type of NIM and the number of the unit cells. The results can lead to possible information for designing new types of narrow tunable filters at microwave frequency.
