Near Field Modeling for THz Wireless Channel in Nettop Size Metal Enclosures

This paper proposes a path loss model and a geometry-based statistical model for Terahertz (THz) chip-to-chip wireless communication in nettop size metal enclosures. The proposed path loss model captures the attenuation of traveling wave and the gain of the electromagnetic horn in near-field region, also the resonant modes in the metal enclosure. The proposed geometric channel model describes the propagation of the traveling wave and the wave generated from the excited walls as a superposition of line of sight (LoS) and multi-bounced (MB) rays. Measurements for LoS propagation in near-field region have been performed in the indoor environment and in a nettop size empty metal enclosure. A good agreement between the measured and model predicted results has been observed, which proves the validity of the proposed models.
