Dual Image Dielectric Guide (DIDG) for Polarization Diversity Applications at Millimeter Wave Frequency
Bibliographic record
Abstract
In this paper, a dual polarized dielectric waveguide is proposed for polarization diversity applications in millimeter wave frequency. The waveguide consists of a squarish dielectric slab attached to two orthogonal vertical and horizontal conductor walls. These walls act as image planes resulting in dual polarized mono-mode region with the same propagation constant for Ey11and Ex11modes. Additionally, two sets of planar transitions exploiting the conductor walls are designed to excite the orthogonal modes as well as provide hybrid circuit integration. The transitions bandwidth (BW) is 3GHz covering 27 to 30 -GHz millimeter wave frequency band. Measured insertion loss of the proposed guide integrated with transition in each side is around 2.7 dB. Isolation between the two orthogonal modes is measured better than 15 dB. Simulated and measured propagation constant of the proposed guide are well-matched.

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.
