High efficient linear polariser using FSS structure
Bibliographic record
Abstract
A linear polarisation converter surface with broadband and high‐efficiency properties is proposed. The proposed frequency selective surface (FSS) polariser consists of two‐corner‐cut diagonal rectangular printed on a substrate backed by a pinwheel loop shape ground. The combination of two‐corner‐cut diagonal rectangular patch and pinwheel loop shape ground contributes to bandwidth expansion. Numerical results indicate that the FSS structure is capable of converting x or y polarised incident wave to the relevant cross‐polarised wave in a wide frequency range from 7.5 to 24.5 GHz with a fractional bandwidth of 106% for −10 dB reflection amplitude. In addition, the and reflection coefficients of the proposed unit‐cell present slight variation for different incident angles up to 40°, which verifies the applicability of the proposed FSS structure in a practical environment. For experimental validation, a prototype of the FSS structure is fabricated and reflection parameters of the proposed structure are measured which agree well with corresponding simulations. Due to the minimal dependency on the angle of incidence and non‐uniform ground plane the proposed polarisation converter unit‐cell can be a possible choice for secure building applications.

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.
