Reflecto-Transmittive Antenna using Active Frequency Selective Surfaces
Bibliographic record
Abstract
A novel reflecto-transmittive antenna is presented using active frequency selective surface (AFSS). The reflecto-transmittive screens are shaped resembling to parabolic reflector. The structure consists of an AFSS array, and a patch antenna used a feed. Each element in the array contains of two rectangular shaped patches connected with each other by a high-frequency pin-diode. By switching the diode between ON and OFF states, the reflection and transmission characteristics of the element are controlled. Three AFSS panels are used to investigate the potential of the antenna in reflecting and transmitting the radiation beams. To shape the proposed antenna with parabolic reflector, two panels beside the central are rotated to various angles. The proposed antenna results in maximum directivity of 11.9 dBi for ON state (reflection), while a 7.8 dBi for OFF state (transmission). The maximum directivity is achieved when 15 ô rotation angle is applied to side AFSS panels towards the feed. The antenna performance is evaluated at 2.45 GHz. The performance of the proposed antenna is compared with an antenna designed with PEC in the same environment. The obtained results show a good agreement.

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.
