| Abstract(in English) | We have been inventing a new encrypted methods to improve physical-layer security of wireless communication. As one of candidates, we propose a method using high-directivity THz Waves. In this system, two encrypted signals on the THz waves are radiated from different directions, and a receiver can decrypt the signals only at the point where the two signals are overlapped. In this report, we demonstrate the results of feasibility confirmation of the proposed method both by homodyne detection and by heterodyne detection. |
