Simulation Analysis of Symmetrical and Unsymmetrical Shape Left-handed Transmission Lines Based on the Uniplanar Double Spiral Resonators
Bibliographic record
Abstract
The uniplanar double spiral resonator is a kind of left-handed unit which does not require the defected ground and can be miniaturization.Through simulation method,we mainly investigated two kinds of transmission lines:symmetrical shape and unsymmetrical shape,composed of uniplanar double spiral resonators.Using HFSS,the return loss and inserted loss characteristic was simulated and analyzed.It was found that the unsymmetrical shape transmission line had better electromagnetic characteristic than the symmetrical one.Next,two groups of simulation experiments were proposed for comparison in order to analyze the phase properties of the given transmission lines.In one simulation,the phase of symmetrical shape and unsymmetrical shape transmission lines was compared.In another group,the phase of the transmission line composed of one unit and the unsymmetrical shape one composed of four units was compared.It was concluded that the unsymmetrical shape transmission line based on uniplanar double spiral resonators was left-handed.

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.
