Crosstalk Reduction Enabled by Hybrid Metallo-Dielectric Waveguide Architecture
Bibliographic record
Abstract
Although substrate-integrated non-radiative dielectric (SINRD) waveguides have demonstrated an excellent potential for THz applications, they suffer from a high level of crosstalk when two or more paths intersect with each, which is inevitable in integrated circuits and systems. In this work, hybrid metallo-dielectric waveguide (HMDW) architecture is used to reduce such crosstalk of intersecting guides. Metal layers outside the intersection of two SINRD waveguides are removed to create substrate-integrated dielectric waveguide (SIDW), thus forming a mode-selective interface to suppress certain undesired mode in connection with crosstalk. Moreover, leveraging SIDW beyond the intersection helps reduce conductor loss. Simulation shows that a 6.1 mm back-to-back substrate-integrated hybrid metallo-dielectric (SIHMD) waveguide with six identical intersections has an average insertion loss of 3.5 dB, whereas the SINRD counterpart has that of 7 dB over the frequency band from 268 GHz to 296 GHz. Simple geometric feature and metallized-viafree manufacturing process of the proposed topology for reducing crosstalk are set to significantly relax manufacturing requirements in THz.

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.
