Broadband Terahertz Hybrid Twisted Horn Antenna for the Electric Field Polarization Manipulation of Spintronic Terahertz Radiation Emitters
Bibliographic record
Abstract
With wireless communication frequencies steadily approaching the terahertz (THz) band, research into devices for on-chip wireless THz communication systems is at its zenith. In this work, we utilize two-photon lithography techniques to fabricate a continuous twisted waveguide exhibiting at least 90% electric field polarization rotation efficiency from 1.0 to 3.0 THz, as well as a hybrid twisted pyramidal horn antenna capable of both polarization rotation and beaming, with a 10 dB bandwidth of 1.7 THz (from 0.3 to 2.0 THz), providing a maximum gain of 12 dB at 1.1 THz, and having a wideband operating region with 90–100% polarization rotation efficiency from 0.3 to 1.75 THz. Due to their versatility and their innate ability to perform multiple functions such as guiding and beaming THz radiation from spintronic THz radiation emitters while manipulating their electric field polarization, we envision such structures to be used for on-chip applications similar to their microwave counterparts, eliminating the need for multiple elements such as antennas, waveguides, and polarizers on dense chips where device footprint comes at a premium.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
