An analysis of terahertz imaging characteristics of dual mirrors antenna

A terahertz imaging structure, which is composed by a duel mirrors antenna and a chip antenna array in focal plane, is proposed and analyzed. The field distribution in the focal plane and the coupling efficiency between the field in the focal plane and chip antenna array are presented. It will be important reference value for developing terahertz imaging system.
