Abstract

fetched live from OpenAlex

In this paper, we will introduce a novel leaky-wave antenna based on the half-mode substrate integrated waveguide. By modifying the aperture of the proposed antenna, the side-lobe level of the radiation pattern in the E-plane is reduced up to -19 dB. The operating band of the antenna is from 27 to 29 GHz that is one of the allocated 5G bands. The radiation efficiency is increased to 53 % by partial removal of the dielectric layer that leads to the reduction of the scanning speed. Hence, the frequency sensitivity of the radiation pattern decreases. The length, width, and height of the antenna are 70mm, 11.5mm, and 0.127mm, respectively. The small size of the antenna makes it a suitable candidate for circuit integration.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
