Abstract.

Epsilon-negative (ENG) and mu-negative (MNG) materials are successfully realized by using composite right/left-handed transmission line (CRLH TL), based on which the photonic crystals were also constituted. The simulated and measured scattering parameters and phase shift indicate that the photonic crystals containing single-negative (SNG) materials can possess zero-effective phase (zero-Øeff) gaps, which are insensitive to the scaling change of the respective unit length. The width and depth of zero-Øeff gaps can be adjusted by varying the ratio of the length of ENG and MNG materials. The characteristics can be utilized to design a compact high quality factor (high-Q) filter, which is demonstrated by a defect mode in the photonic crystals in experiments.
