Dictionary / Coil & Geometry
Coil Type
Coil & GeometryA classification of the electromagnetic coil inside the accessory based on its measured field distribution. A Pancake Coil produces a center-dominant field with peak strength at the center and rapid falloff outward. A Donut Coil produces a ring-dominant field with peak strength in a ring around the center and a weaker center. A Loop Coil concentrates energy along the wire path. Coil type is detected automatically from the scan data by comparing ring zone field strength to center field strength. For multi-coil mats (rect shape), single-coil-type detection doesn't apply. Instead the report uses Coil Count, Coil Layout, and Coverage Uniformity to describe the mat's collective behavior.
