We propose a dual-band transparent window terahertz metamaterial consisting of a closed-ring resonator and a square patch. This structure can achieve two transparent windows with transmission intensity of more than 90%. The formation of the two windows can be attributed to the coupling of the localized resonance modes between the closed-ring and square patch. The influence of the geometrical dimensions of the closed-ring resonator and the square patch on the transmitted spectrum is also discussed; it is found that the change of sizes can strongly affect the frequencies of the two transparent windows. This novel terahertz metamaterial may open up new avenues toward the control of terahertz waves in many technology-related areas.
