Outline of Final Research Achievements |
I have developed an active polarization filter which is able to switch the polarization state of the transmission light between the right and left circularly polarizations in terahertz (THz) frequency region where the wavelength is several hundred micrometer. Utilization of the polarization light, which presents an aligned oscillating electric field, enables us to obtain detailed material information at spectroscopic measurement. Moreover, dynamic switching of the polarizations provides further precise measurement. There has however been no active filter to switch the polarization states in THz region. I developed a THz metamaterial device to switch polarization states of the THz wave dynamically. The metamaterial is composed of array of reconfigurable metal spirals, which are 150-μm in diameter using Micro electro mechanical systems (MEMS) technology.
