Abstract

fetched live from OpenAlex

A deep learning-based approach for full-functionality modeling of broadband radio frequency (RF) devices is presented. As a case study, a septum-based orthomode transducer (OMT) with an equilateral triangular common port is analyzed over a 46% fractional bandwidth. A dataset of 729 scattering matrix responses, generated by varying five OMT dimensions, is used for training. Instead of treating frequency as a direct input, the deep neural network (DNN) exploits its implicit structure, capturing patterns and similarities with high computational efficiency. The model's generalization is validated on two test cases, demonstrating fast and reliable wideband RF modeling. Moreover, its extrapolation capability is assessed using a third case with dimensions that fall outside the training range, highlighting its generalization and effectiveness.

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.
