Prototyping of Novel Isolator Design Based on Cavity Magnonics
Bibliographic record
Abstract
The cooperation of coherent and dissipative coupling produces nonreciprocity in cavity magnonic devices, in which the isolation ratio can theoretically be infinite at a matching condition (zero-damping condition). In this article, we report the design of such a prototype, where a yttrium–iron–garnet sphere is strongly coupled to a planar microwave cavity resonator. Three different microwave isolator design schemes have been constructed according to the latest developed theory, resulting in considerable isolation, design flexibility, and device size reduction. Fabricated devices achieved the isolation of 65.8, 40.5, and 31.0 dB and the corresponding insertion loss of 23.6, 0.7, and 0.7 dB, respectively. These devices promise to be useful in microwave range applications that demand miniature, low cost, and narrowband. Furthermore, our magnonic device may open a promising way for signal processing through the manipulation of coherent and dissipative coupling.

How this classification was reachedexpand
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.
