Simultaneous Specific Absorption Rate Ratio Summation and Peak Location Separation
Exceeding simple SAR summation thresholds requires peak location separation ratios below 0.04 to avoid multi-thousand-dollar volumetric chamber testing.
Volumetric SAR Scan
Meaning
Maps localized radiofrequency energy distribution across a three-dimensional grid volume within a phantom fluid during automated SAR testing. Executing a volumetric sar scan allows evaluation software to calculate spatial-peak power absorption averaged over one-gram or ten-gram tissue masses. Automated robot arms step electric field probes through discrete grid points surrounding peak absorption regions.
The resulting three-dimensional measurement matrix enables spatial energy integration and maximum exposure assessment.
Grid Interpolation
High-resolution volumetric measurements record E-field magnitude at precise spatial coordinates throughout phantom liquid volumes. Interpolation algorithms process discrete measurement grid data to reconstruct continuous spatial energy distributions. Post-processing software calculates localized SAR values at positions between physical probe measurement locations.
A volumetric sar scan provides detailed spatial field maps required for compliance evaluations.
Peak Volume Extraction
Specialized algorithms search three-dimensional grid data to locate peak exposure cubes within phantom fluid volumes. Spatial integration routines average absorbed power density over cubic volumes corresponding to exact tissue weights. Analysis software identifies secondary absorption peaks when evaluating complex multi-antenna device architectures.
Extrapolation algorithms estimate field behavior near phantom shell surfaces where physical probe placement is mechanically restricted.
Compliance Artifact
Data generated during three-dimensional volume scans is converted into spatial contour plots and numerical field matrices. Generated files become permanent records within formal laboratory compliance test reports. The volumetric sar scan artifact verifies regulatory compliance for wireless device authorization.
