Four-Mode Switchable Frequency-Selective Surface Featuring Wideband and Angular Stability
Bibliographic record
Abstract
This letter proposes a switchable frequency-selective surface with wide-band and angle-stable characteristics, which could independently manipulate the TE and TM incidences through four modes. Distributed compensation capacitors are designed to solve the problems of unequal impedances and inconsistent responses under different polarizations caused by the asymmetric structure. It also helps improve the miniaturization and oblique-incident performances of this work. Additionally, the transmission responses and field distributions of each layer are studied to verify the proposed principle. The operating mechanism under different waves is also analyzed through two equivalent-circuit models. The results show that the design achieves stable transmission and shielding behaviors from 0° to 55° incidences. In the transmission state, a passband of 32.9% is realized with a minimum insertion loss of 0.15 dB, while the shielding performance can be observed from low frequencies to 10 GHz. Finally, a prototype is fabricated, and reasonable measurement results are obtained.

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.
