Terahertz Polarimetric System Based on Polarization Sensitive Frequency Selective Surfaces
Bibliographic record
Abstract
We demonstrate a novel and cost-effective terahertz polarimetric system by incorporating a set of polarization sensitive frequency selective surfaces (PS-FSS) and Schottky diode detector with ultra-fast acquisition system. Those PS-FSSs are placed in a rotatable wheel with four distinct orientations such as 0°, 45°, 90° and 135° to calculate Stokes' parameters (S<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</inf>, S<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</inf>and S2 parameters). Here, frequency dependent polarization changes are being investigated in the case of 1.0 mm thick stacked quartz crystal at center frequency of 0.41 THz. From experimental results, it is noticed that through the rotation of PS-FSS chopper, we could extract the Stokes' parameters at 0.41 THz for each rotation angle of the sample in a very short time using this proposed compact and simple system.

How this classification was reachedexpand
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.
