Terahertz antenna-channel codesign for integrated sensing and communication in the near field
Terahertz (THz) systems in the range of 100 GHz–10 THz combine large apertures and short wavelengths, resulting in an extended radiative near field where spherical wavefronts dominate electromagnetic propagation. In this near-field (NF) realm, classical far-field beam steering and stationary channel assumptions break d...
