%J 中国物理快报 %D 2008 %I %X Single-negative materials based on photonic crystal with multiple defect layers are designed and the free modulation of defect modes is studied. The results show that the multi-defect structure can avoid the interference between the defect states. Therefore, the designed double defect modes in the zero effective-phase gap can be adjusted independently by changingthe thickness of different defect layers. In addition, the two tunable defect modes have the omnidirectional characteristics. This multi-defect structure with above-mentioned two advantages has potential applications in modern optical devices such as tunable omnidirectional filters. %K 42 %K 70 %K Qs %K 41 %K 20 %K Jb %K 78 %K 20 %K Ci %K 42 %K 25 %K Bs
