摘　　要：An effective highly dispersive medium is proposed by utilizing strong dispersion of localized defect mode in a microstrip photonic crystal. Linewidth narrowing in a composite microstrip resonator using this photonic- crystal-based effective medium is investigated and its dependence on the structure parameters is presented. Both numerical simulations and experimental results demonstrate that compared to the traditional resonator, the Qfactor increases much more quickly and the peak transmission decreases more slowly at the same time for the composite resonator.An effective highly dispersive medium is proposed by utilizing strong dispersion of localized defect mode in a microstrip photonic crystal.
