Accurate parameter extraction and joint field/circuit model of uniplanar and multi-layer microwave and millimeter wave monolithic and hybrid integrated circuits and antennas
Bibliographic record
Abstract
Unified joint field/circuit model is proposed and developed for accurate representation of uniplanar and multilayer integrated circuits. It is realized through the use of a newly proposed parameter extraction scheme that is called "short-open calibration" (SOC) and it is self-contained in a full-wave method of moments (MoM). This SOC is used to evaluate and to remove unwanted numerical error terms in the 3-D MoM simulation. Following a brief description on our SOC and 3-D MoM, a variety of uniplanar and multilayer circuits and antennas are characterized as their field/circuit models that involve all physical effects. SOC-extracted circuit parameters are obtained for uniplanar FGCPW structures, microstrip-fed slot radiator and layer-to-layer transition that are also well verified by our measurements. The models developed in this work are useful not only in gaining physical insight into their electrical behavior and also in applying efficient circuit network-oriented optimization approaches.

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.
