The need to correctly predict the voltage across terminals of mm-sized coils, with ferrite core, to be employed for magnetic stimulation of the peripheral neural system is the motivation for this work. In such applications, which rely on a capacitive

Previous reports of magnetic stimulation of the peripheral nervous system (PNS) used various coil geometries, all with outer diameters larger than 35 mm, and stimulation energies in the 50 J range to evoke neural excitation. Recent reports of central

Resonance-based wireless power delivery is an efficient technique to transfer power over a relatively long distance. This technique typically uses four coils as opposed to two coils used in conventional inductive links. In the four-coil system, the a

Low-frequency (1-20 MHz) inductive coupling is a leading technique to power biomedical implants wirelessly. Even though these are non-radiating systems, the external and the implant coils can cause sufficient radiated electric field to exceed the fed

Electromagnetic numerical methods, such as the finite element method (FEM), admittance method (AM), or finite-difference time-domain (FDTD), often use models that are discretized based on the dielectric properties of included materials. When studying

Magnetic stimulation, as a means of evoking neuromuscular activity, has an advantage over direct electrical stimulation in that the stimulator need not directly contact the neural tissue. However, the high energy levels and large magnetic coils neede
