Terahertz (THz) communication has been regarded as one promising technology to
enhance the transmission capacity of future Internet-of-Things (IoT) users due to its ultrawide
bandwidth. Nonetheless, one major obstacle that prevents the actual deployment of THz lies
in its inherent huge attenuation. Intelligent reflecting surface (IRS) and multiple-input-
multiple-output (MIMO) represent two effective solutions for compensating the large path
loss in THz systems. In this article, we consider an IRS-aided multiuser THz MIMO system …
