报告摘要

Recently, the tunability of metamaterials has been widely investigated as their tuning capabilities could broaden the working bandwidth and enable reconfigurable metamaterials devices. These tunable metamaterials with negative refractive index properties have been demonstrated by sophisticated fabrication technology and optimized designs. The tuning methods are often used to adjust the resonant frequency by means of semiconductor diodes, or by changing the surrounding media, which are the passive control of the properties of the metamaterials and highly dependent on the nonlinear properties of the nature materials. On the other hand, MEMS technology has been well developed for fabrication and actuation of complicated micromechanical devices with extreme performance and flexibility. That has been well developed for active control of metamaterials and enabling complicated 3-D micromechanical devices. This technology provides an ideal platform to directly reconfigure unit cells of the metamaterials, which overcomes the limitations of metamaterials composition through the use of bulk silicon micromachining.

In this talk, I will present (1) metamaterials physics; (2) the electromagnetic controllability of metamaterials in visible, infrared, and THz wavelength ranges; (3) active control of metamaterials by using MEMS based metamaterials; (4) tunable metamaterials in optical sensor applications.
