Novel Dual-Polarization Multimode Artificial Frequency-Selective Surface With Independently Reconfigurable Windows for Different Frequencies
Bibliographic record
Abstract
In this article, a novel multimode switchable frequency-selective surface filter/shielding is proposed, featuring a reconfigurable–shared–noncoupling structure and a polarization-independent control function. Compared to most conventional dual-mode polarization-insensitive structures, this design offers the capability to independently control TE and TM waves at different frequencies through four states. According to equivalent circuit models, two basic dual-layer single-polarization structures are applied to achieve the switchable transmission and shielding states for two polarizations at different frequencies, respectively. Based on this, an improved multilayer structure is designed with the orthogonal reconfigurable–noncoupling layers and a shared interlayer. It could control the operating wave without the effect of the cross-polarized wave, which successfully obtains the polarization-independent efficient transmission and full shielding modes on one structure. The proposed structure has the TE- and TM-independent manipulated transmission windows at 3.8 and 5.2 GHz, the full shielding mode within 1–6 GHz, and excellent angular stability up to 60°. Finally, a prototype is manufactured, and the measured results are in good agreement with the simulation ones, demonstrating that the concept of polarization independently controlled active frequency-selective surface has a potential application prospect in radomes and electromagnetic interference shielding.

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.
