Microwave Absorbing Features of Ce2(Co0.3Fe0.7)17/Ferrite Coating Material
Bibliographic record
Abstract
This paper attempts to combine Ce2(Co0.3Fe0.7)17and Co2Z-type hexagonal ferrite (hereinafter referred to the ferrite) into a composite with excellent absorbing properties.Firstly, the permittivity and permeability spectra of Ce2(Co0.3Fe0.7)17/epoxyresin composite were investigated, so were those of the ferrite/epoxy resin composite.On this basis, the author prepared coaxial Ce2(Co0.3Fe0.7)17/ferrite/epoxyresin composite specimens at different volume ratios of the Ce2(Co0.3Fe0.7)17particles and the ferrite particles, and also studied their permittivity and permeability spectra in the frequency range of 8~18 GHz.In this way, the optimal volume ratios of both types of particles were determined for the composite.Through the analysis, it is concluded that, based on the matrix of epoxy resin and polyamide, the singlelayer plate absorber specimens can control the reflection loss within -10dB across the frequency range 8~18GHz, when the thickness is 1.1 mm, the fraction volume of Ce2(Co0.3Fe0.7)17 is 25 % and the fraction volume of ferrite is 20 %.

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.
