Abstract Next generation communication systems go to tetra‐hertz (THz) frequency bands. In this article, low‐complexity but near‐optimal hybrid beamforming design is investigated in THz by considering its unique channel characteristics and disc

Terahertz (THz) absorbers with high absorptivity across a wide frequency band have attracted considerable interest. In this paper, we present the design of an ultra-broadband THz metamaterial absorber with high absorptivity based on a single-layer sq

We propose to combine a circularly polarized first-color laser with a linearly polarized second-color laser to control the polarization of THz radiations in the low-frequency region from single-layer graphene. We find that the THz ellipticity can be
