Abstract
The present disclosure relates to a terahertz wave generation apparatus capable of wavefront control. A terahertz wave generating apparatus according to an exemplary embodiment comprises a photoconductive substrate; and a plurality of terahertz wave generating unit elements arranged in a two-dimensional array on the photoconductive substrate. Also, the terahertz wave generating unit elements comprise a plurality of first electrodes arranged in the two-dimensional array on the photoconductive substrate and respectively connected to a plurality of first electrode pads, and at least one second electrode formed on the photoconductive substrate so as to face the first electrodes.
