Abstract Firstly, the transmission properties of the heterostructure constructed by two kinds of single-negative metamaterials were investigated and the results showed that the single-negative metamaterial heterostructure can play the role of the subwavelength cavity. In addition, the enhancement of the Q-factor of the subwavelength cavity was also studied and it was found that the Q-factor of the subwavelength cavity can be greatly increased when the electromagnetically-induced-transparency-like metamaterial unit is loa-ded at the interface of the single-negative metamaterial heterostructure. Therefore, a high Q-factor subwavelength cavity was realized based on the single-negative metamaterials. The cavity may be useful for miniaturization of devices and elements in microwave or higher frequency range.

Key words： metamaterials cavity subwavelength high Q-factor
