Abstract

fetched live from OpenAlex

Abstract We report the physicochemical insight into the role of coral‐shaped yttrium‐iron‐garnet (YIG) particles for high electromagnetic interference (EMI) shielding behaviour of YIG‐polyaniline (PANI)‐Wax composites. We studied the total shielding effectiveness (SE T ) of various compositions of the composites in X and K u ‐band frequencies (8‐18 GHz) and came upon with a critical concentration (20 wt% of YIG) for which SE T is maximum (‐44.8 dB). At this critical concentration, the coral shape of YIG helps in effectively increasing the YIG‐PANI interfaces necessary for the multiple scattering of electromagnetic (EM) waves. The scattered microwave is then trapped within the dense coral‐network of YIG until they are absorbed therein by PANI via conduction loss; thereby, dramatically enhancing the microwave attenuation. The detailed EMI shielding mechanism is explained based on electrical and magnetic properties of the composites. Our result demonstrates the importance of morphology of the dielectric/magnetic particles and their concentration in the composites for designing an efficient EMI shield.

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.
