Abstract

fetched live from OpenAlex

Meshless methods are emerging as a new class of numerical techniques for modeling complex electromagnetic problems with irregular geometries. To apply them to open structures, effective absorbing boundaries need to be developed. In this paper, the perfectly matched layer (PML) absorbing boundary condition is implemented into the meshless radial point interpolation method (RPIM) for accurate meshfree modeling of electromagnetic radiation problems in time-domain. Two benchmark radiating structures, a parallel waveguide and a conical unipole antenna, are presented to validate the effectiveness of the implementation. Comparisons are made between the numerically computed results and the measured results from previous reports and good agreements are found. In contrast to conventional FDTD technique, the RPIM modeling with the PML condition requires much less computational efforts for antenna radiation problems, thanks to its capability of conformal modeling and multi-scale solutions.

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.
