Quarter-Mode Dielectric-Filled Resonators Based on Virtual Magnetic Walls
Bibliographic record
Abstract
A compact quarter-mode (QM) dielectric-filled resonator (DR) is proposed, along with a design methodology employing virtual magnetic walls (VMWs). The operating principle of the QM DR is discussed, focusing on the realization of VMW through an open aperture (OA), which eliminates the aspect ratio limitation. The implementation of VMWs is analyzed using transmission line theory. Compared to conventional full-mode (FM) resonators, the proposed QM DR achieves a 67% reduction in size and weight. This compact design makes the QM DR well-suited for the development of compact bandpass filters (BPFs), offering enhanced out-of-band selectivity. To validate the proposed approach, a fourth-order QM DR BPF was designed, fabricated, and experimentally tested. The experimental results confirm the improved out-of-band selectivity, demonstrating the effectiveness of the proposed design.

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.
