| Research Abstract |
In this research program, we have developed "programmable metamaterial circuits" which can enable us to control the optical response arbitrary and actively in terahertz region. Simulation results were shown that a split-tube array structure on a Si substrate irradiated with a CW light source can modulate amplification and phase of THz wave near the resonance frequency. The behavior of modulation was observed in our experiments although the signal was smaller than the simulation.
