Abstract

fetched live from OpenAlex

Residual stress gradient is unavoidable in thin-film based devices such as radio frequency (RF) micro electro mechanical systems (MEMS) switches. In this paper residual stress gradient is modelled which affect the frequency shift in RF-MEMS switches. Curvature of thinfilms are measured experimentally and then residual stress gradient is modelled analytically and using finite element modeller (FEM). A comparison between analytical model and FEM has been carried out by introducing the initial upward curvature due to residual stress in the model. Beams under residual stress gradient change the pull-in voltage and shows frequency shift which points out that underestimating such effects can lead to inaccurate design and analysis of RF-MEMS switches and subsystems.

Not 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.
