Abstract
This letter presents the first measured results of sub-THz photoconductive evanescent-mode (EVA) waveguide single-pole single-throw (SPST) switches operating in the G-band. Both second- and third-order devices are designed, fabricated, and measured, resulting in low insertion losses (ILs) of <0.4 dB and electronically tunable isolation reaching >50 dB while requiring low optical powers. An analysis of the solid-state plasma (SSP) physics reveals the viable potential for switching at frequencies above 800 GHz, emphasizing the promising capabilities of this enabling platform technology for future 5G/6G communication and radar sub-THz applications.

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 it
