Abstract

fetched live from OpenAlex

A novel Cerenkov-transition based high-frequency/high power backward wave oscillator (BWO) is presented. The proposed device is a defected metallic triangular lattice photonic crystal (PC) structure that has no axial discontinuities. The absence of the axial discontinuity and low axial DC magnetic field requirements allows for simple fabrication process. Isolation between the generated electromagnetic fields and electron beam offers easy field extraction and coupling to the output loads. Design of the proposed device was carried out with a first principles based combined FDTD/PIC simulator developed for this work. Typical design examples presented here demonstrate the potentials of the proposed structure. The PC based structure allows easy tunability and scaling to higher frequencies.

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.
