Abstract
A subwavelength terahertz switch using an artificially designed conductor metamaterial is discussed in this invention. Slow-light EM Wave propagating at THZ speed imitates the strongly localized surface plasmon modes and henceforth is called Spoof Surface Plasmon Polariton (SSPP) in this invention. The SSPP mode of slow-light EM propagation can be easily tailored by changing the refractive index of the dielectric materials inside the metallic gap structure engineered as a periodic array of grooves. Thus, the incorporation of electro-optical material which has birefringence such as a nematic liquid crystal (N-LC) or multiple refractive indices into the metallic gap leads to a highly compact and efficient terahertz switch being controlled by a low voltage signal. The THZ dynamic switches can be used to construct linear switches, Y junction switches and Mach Zehnder interferometers.
