Substrate integrated circuits concept applied to the nonradiative dielectric guide
Bibliographic record
Abstract
A novel technique for designing and realising nonradiative dielectric (NRD) waveguide circuits based on the concept of substrate integrated circuits (SICs) is proposed and demonstrated for the first time. In this new scheme, the substrate integrated NRD (SINRD) guide is created or synthesised by drilling a pattern of air holes in a planar dielectric substrate. Furthermore, metallised holes are also introduced to enclose the NRD guide. Using this configuration, an integrated waveguide transition and mode suppressor can be realised. Dispersion analysis and design considerations for the proposed structure are presented and discussed. It is shown that this new approach can be applied over a wide range of microwave and millimetre-wave frequencies for high-density circuit integration and low-cost system applications. Measured results of a number of showcase circuits validate the design method, which include a bandpass filter, a directional coupler and an integrated transition between an SINRD guide and a rectangular waveguide.

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.
