| Summary: | Miniaturization of NMR detector is a trending research area. This report suggested to use Helmholtz coil configuration to enhance the sensitivity and resolution of the NMR detector. Scaling Helmholtz coil down to Helmholtz micro-coil will face various disturbance and the standard Helmholtz coil equation might not be as accurate. Hence, step by step selection of parameters such as coil thickness, trace width, number of turns are carefully simulated using CST software. The final NMR detector model has rectangular spiral micro-coils in Helmholtz configuration, separated with polyimide as dielectric material, buried in silicon substrates to achieve excellent magnetic field uniformity at the destinated area. |
