Abstract

This work is focused on wideband terahertz (THz) beam/focus scanning reflectarrays/mirrors, to provide beam scanning solutions to THz real-time imaging systems. For the THz reflectarrays, frequency beam scanning method previously proposed by our group is experimentally verified in a frequency band of 200 ∼ 300GHz. Meanwhile, the common mechanical scanning by offsetting the feed is also numerically provided. Based on similar idea, a THz mirror with plane wave incidence is also investigated in order to obtain a frequency scanning focus over a large frequency band. The simulated results are given in this paper. The proposed idea can also be extended to a mirror with frequency scanning focus as it is illuminated by a feed close to the mirror aperture.
