Study of effects of HTSC nonlinearity on current distribution over a microstrip line
Bibliographic record
Abstract
The applications of high temperature superconducting (HTSC) microwave circuits are limited to low power levels. The surface resistance of HTSC materials increases significantly with the power. For some applications, such as the transmitters in the base station of wireless communication systems, we have to push the input power level high enough to meet practical requirements. It is necessary to investigate the nonlinear effects of HTSC planar microwave integrated circuits at these high power levels. In this paper, a HTSC microstrip transmission line is analysed to investigate the nonlinear effects on the current distribution due to high applied powers. The current density distribution and the power handling capability of the HTSC planar microstrip line are studied, and the conductor loss as a function of the applied power obtained. In this study, a new approach based on combination of the moment method (MoM) and harmonic balance (HB) technique is used for the analysis of high power nonlinearities in HTSC planar microwave circuits. The field interactions and fringe fields outside the superconductor are included in the MoM formulation by using appropriate Green's functions, and the nonlinear analysis is carried out by the HB technique.

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.
