Figure 6.

Electric field distributions for the proposed coils with different tilting angles based on the simulations and experimental measurements; Both the 2D and 3D distributions of the electric field were simulated. All the experimental measurements were performed at a 1.5 cm distance from the coil’s lowest point with 5 mm lateral steps using calibrated vector-field probes. All the data is normalized to the highest electric field intensity. In the experimental data, the scanned area for the coil-B and the figure-8 coil is larger than the coil-A series due to their larger size, which resulted in more pixels for the two coils.
