Abstract :
The polarization response of THz wavelength metamaterials modulators have been researched, and a special modulator structure has been proposed, simulated and fabricated. Compared with the traditional split ring resonator modulators which are all polarization sensitive, the new structure has properties of polarization insensitive. The structure is a completely symmetrical metal structure and has the perfect characteristics of the polarization insensitive.
