Dual-Band Full-Space Scanning Leaky-Wave Antenna Based on Ferrite-Loaded Open Waveguide
Bibliographic record
Abstract
A dual-band full-space scanning leaky-wave antenna based on a ferrite-loaded open waveguide structure is proposed. The lowest three bands of this structure are: the composite right/left-handed (CRLH) mode with positive group velocity first reported recently, the traditional isolator edge-guided mode, and a mixed forward/backward perturbed waveguide mode with a negative group velocity in its leaky-wave region. The leaky-wave regions of the CRLH and of perturbed waveguide modes are exploited to provide dual-band radiation. Due to their opposite group velocities, the two modes have their ports placed at both ends of the structure, which allows independent matching sections and also avoids the necessity of a diplexer. The antenna was demonstrated by both full-wave simulation and by experiment.
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 imitationNot 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.
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 teacher head, not a consensus.
