Spatial-Filtering Microwave Devices Using Metallic Anisotropic Grids Over Ground
Bibliographic record
Abstract
In this review article the authors examine interesting resonance phenomena that result due to peculiar dispersion characteristics of continuous (unloaded) anisotropic grids along with corresponding applications. The phase space (k-space) of these metallic grids at resonant frequencies is characterized by isofrequency dispersion contours that have rectangular and hyperbolic shapes. As a result, energy propagation takes place in specified directions within the periodic structures, an effect called 'self-collimation'. Novel spatial-filtering and wave-guiding devices could be implemented using these properties. Two such spatial-filtering devices using different configurations of anisotropic metallic grids will be reviewed: a microstrip harmonic splitter that separates 3 GHz from its 6 GHz harmonic and a highly selective 5.8/6.2 GHz microstrip diplexer

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.
