Abstract
In this letter, a novel terahertz (THz) wave switch based on metamaterial is proposed and measured.Onβoff switching is based on a controllable resonance of the metamaterial by applying an external semiconductor laser to illuminate substrate. Experimentally, we demonstrate onβoff response time speed and extinction ratio of the proposed THz wave switch is of 1 ms and 19.4 dB at 0.32 THz, respectively. The presented THz wave switch has a potential application to THz wave communication systems. Β© 2010 Wiley Periodicals, Inc.

We designed and demonstrated experimentally a terahertz wave switch utilizing microstrip resonator structure. The switch mechanism of the presented terahertz wave switch is based on the resonance charactersitic of resonator microstrip structure controlled by without or with light excitation. The exp
