Design and Characterization of the EBG Waveguide-Based Interconnects
Bibliographic record
Abstract
An alternative signal guiding structure, which can be integrated within the printed circuit substrates, is investigated in this paper. The structure is realized by forming a rectangular waveguide in a 2-D electromagnetic bandgap (EBG) substrate. In this manner, a bandpass interconnect is provided that proves to be a promising technology for the high-speed/high-frequency system design. A systematic approach to the design and optimization of this interconnect is presented here followed by investigation of various bend geometries. The studied structures exhibit very low levels of loss and leakage when inspected at tens of gigahertz frequency range. Moreover, the near-end and the far-end crosstalks are monitored in multiple interconnects proving the high efficiency of this alternative routing structure in dense layouts. Nonetheless, the crosstalk performance is degraded as the coplanar microstrip-to-waveguide transitions are added. These transitions are essentially tapered microstrip lines that are connected to other circuitries. Continuous via fences are inserted in the transition sections of multiple structures demonstrating significant improvement in the crosstalk performance.

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.
