| Research Abstract |
Novel terahertz resonators using total reflection and surface-plasmon resonances were studied, in order to achieve sensitive terahertz spectroscopy of biological tissue. Local-field enhancement of terahertz wave was clarified by finite difference time domain (FDTD) simulation of the devices under aqueous environment. High-quality terahertz-wave resonators with various periods were successfully fabricated by using novel process with an organic material (SU-8). Furthermore, widely tunable high-power terahertz wave sources and in situ spectroscopic measurement system of live cell were realized.
