Simulation of bow-tie THz antenna using hybrid finite element method and spectral ray tracing technique
Bibliographic record
Abstract
In this paper, we propose a hybrid method that uses commercially available Finite Element Method (FEM) software and our in-house developed Spectral Ray Tracing (SRT) algorithm. The method is used for calculating the radiation patterns of complex lens antenna such as a bow-tie antenna backed by silicon lens. A traveling-wave terahertz photomixer integrated with a coplanar stripline (CPS) waveguide is used to generate the radiation that couples to the antenna. We employ HFSS, a FEM solver, to model THz propagation along the CPS line and planar bow-tie. Once the near-field distribution is found, the SRT method is then applied to find the radiation patterns and gain of the bow-tie antenna backed by a silicon hyper-hemispherical lens. The results are compared with full FEM simulation of the antenna-lens structure.

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.
