Capture efficiencies estimated by the COMSOL finite element method compared to analytical calculations (Python). Magnetic moment of the cells was chosen such that capture was around 50%, where the designs show the highest sensitivities to variation. The difference is less than 3%.
| Array (mm) | Moment (fAm2) | COMSOL (%) | Python (%) |
|---|---|---|---|
| 1.0 × 2.8, 1.0 × 2.0 | 4 | 47 | 47 |
| 1.0 × 1.5, 1.0 × 1.5 | 6 | 52 | 50 |
| 4.0 × 4.0, 4.0 × 4.0 | 12 | 54 | 51 |
