Abstract

fetched live from OpenAlex

Based on the properties of graphene nano-patch antennas, we propose a reconfigurable multiple-input multiple-output (MIMO) antenna system for Terahertz (THz) communications. First, the characteristics of the graphene are analyzed and a beam reconfigurable antenna is designed. The beamwidth and direction can be controlled by the states of each graphene patch in the antenna. Then the path loss and reflection models of the THz channel are discussed. We combine the graphene-based antenna and the THz channel model, and propose a new MIMO antenna design. The radiation directions of the transmit antennas can be programmed dynamically, leading to different channel state matrices. Finally, the path loss and the channel capacity are numerically calculated and compared with those of the Gigahertz (GHz) channel. The results show that for short range communications, the proposed MIMO antenna design can enlarge the channel capacity by both increasing the number of antennas and choosing the best channel state matrices.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
