英文摘要	The distinctive dispersion of composite right/left-handed transmission-line metamaterial offers a unique way of manipulating electromagnetic waves across a wide spectral range from microwave to the infrared. In this paper, we present a tunable mid-infrared composite right/left-handed metasurface based on the phase-change material of vanadium dioxide. The metasurface consists of an array of 'H'-shaped gold pads separated from a metallic ground plane by a film of vanadium dioxide. As the insulator-to-metal phase transition is thermally triggered, both right-handed and left-handed metasurface modes redshift with reduced absorbance before they are eventually switched off. The tunabilities of right-handed mode frequency and left-handed mode frequency are measured to be approximately 3.6% and 2.7%, respectively. Our demonstrated metasurface with tunable composite right/left-handed dispersion could be useful for beam scanning for a fixed frequency in mid-infrared applications.
