A new optically controlled CDS-polymer capacitor for tunable microwave components
Bibliographic record
Abstract
For the first time, we show that a new optically sensitive MIM CdS-polymer capacitor can provide sufficiently large capacitance variation to be useful for tunable microwave components. The new capacitor, based on photoconductive particle inclusions that cause dielectric permittivity change with light, is demonstrated in a coplanar circuit operating over the 1 to 10 GHz band. Upon illumination through the lower ITO electrode, its capacitance varied from 0.16pF to 0.18pF, a 13% change. A complete equivalent model of the capacitor is given. The basic CPW circuit could easily be modified to overcome present material limitations associated with the optically transparent ITO metal and the CdS polymer mix, leading to future low cost, simply processed, integrated, tunable components such as filters and phase shifters. This new technology allows for the elimination of performance degrading electronic circuitry that has traditionally plagued reconfigurable components.

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; both teacher heads agree on what is shown here.
