Analytical solution for the design of planar electromagnetic bandgap structures with spurious‐free frequency response
Bibliographic record
Abstract
Abstract In this article, an analytical solution is obtained for the design of electromagnetic bandgap (EBG) structures that feature a single stopband without the spurious rejected bands present in the conventional EBG devices at the harmonics of the design frequency.The proposed technique is applied for the design of microwave filters intended for broadband applications, where closed formulas are found both in two‐port lines and in four‐port coupled lines obtaining very good results. The implementation of the EBG structure in coupled lines allows for the redirection of the reflected signal to the coupled port producing a device with input port matched at all frequencies. © 2012 Wiley Periodicals, Inc.

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.
