Abstract

fetched live from OpenAlex

In this paper, a universal LP01 to any LPlm mode converter structure is proposed based on a circular waveguide. As examples, nine mode converters from LP01 to LP02, LP03, LP04, LP05, LP06, LP07, LP11, LP21 and LP31 are designed. It is shown that an insertion loss of less than 3 dB is achieved over the entire C-band for all the mode converters. Furthermore, two mode (de)multiplexers based on directional couplers are demonstrated, showing an insertion loss less than 2.5 dB and a crosstalk less than −10 dB over the C-band.

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.
