A SSPP-Integrated Defected Ground Structure With Low EMI
Bibliographic record
Abstract
Conventional defected ground structures (DGSs) suffer from strong crosstalk and radiation, which limit their use in compact and highly integrated microwave circuits. To address this, this paper presents a spoof surface plasmon polariton-integrated defected ground structure (SSPPI-DGS). By embedding periodic SSPP units into the ground plane, the proposed design exhibits enhanced slow-wave characteristics and strong field confinement, as confirmed through dispersion analysis. Simulated and measured results further validate that the SSPPI-DGS achieves significant suppression of both near-end and far-end crosstalk, with reductions of up to 6 – 7 dB at fundamental frequencies, while simultaneously lowering radiation loss and insertion loss compared with conventional DGSs. In addition, the proposed unit cell occupies a smaller footprint, enabling improved integration density. These findings highlight the SSPPI-DGS as a practical and scalable solution for future low-EMI, high-integration microwave circuits and system-on-package applications.

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.
