Abstract

fetched live from OpenAlex

The Peripherally Excited phased array has been studied as a useful device for scanning a beam through two dimensions, with a simple structure and reduced number of phase shifters. The antenna uses peripheral sources to excite waves in a leaky cavity, which radiate directive scanning beams. This work investigates how using input amplitude control as a degree of freedom allows for the synthesis of shaped beams. Through a simple model of fields in the cavity, a linear system of equations can be constructed and solved for a desired aperture excitation. Examples of binomial and Chebyshev beams, scanned and at broadside show good agreement between theory and simulation.

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.

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.
