Design and Characterization of MSAP‐Fabricated Sub‐THz Frequency Selective Surface by Bench‐Top Optoelectronic Measurement System
Bibliographic record
Abstract
ABSTRACT A low‐cost and compact benchtop using the off‐the‐shelf optoelectronic (OE) measurement system is presented which is built to measure the performance of a 160 GHz frequency selective surface (FSS). The system uses an optical heterodyne source to excite wireless signals through the ‐D‐band (110–170 GHz), and transmission magnitude is measured using a frequency‐extended power spectrum analyzer (PSA). The system is shown to perform well towards characterizing an FSS structure fabricated using a modified semi‐additive process (MSAP), with the magnitude shown to agree well with both full‐wave simulation of the array and measurements taken using a conventional microwave measurement setup. While the noise floor of the measurement system limits the ability to characterize FSS attenuation below –16 dB, the reduction in transmitted power at the design frequency is clearly captured. The OE measurement system represents an approach to analyzing sub‐THz frequency wireless devices that will play an essential role in the development and adoption of next‐generation wireless communications.

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.
