Abstract

fetched live from OpenAlex

A volume integral equation (VIE) formulation was developed by Zhou and Shafai, which can be used for the analysis of scattering from general material bodies. Conductors are treated as a dielectric by letting the permittivity approach infinity. The formulation uses the dyadic Green's function, which is singular when the source and field points coincide. Removing this singularity gives a source dyadic term that is geometry dependent (Yaghjian 1980). In application of the moment method to solve the volume integral equation, using pulse type basis functions, one must sub-divide the object into small cells. With different cell shapes one needs to use the corresponding source dyadic terms, that may influence the performance of the solution algorithm. In this paper, we present an analysis of the dependence of the solution on the cell shape and size. Applications to antenna radiation patterns of circular cylindrical dielectric resonator antennas in particular are discussed.

Full frame distilled prediction

Teacher imitation

Not 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.
