Based on an alternative differentiable objective function which is related with the maximum of current density, an iterative optimization method is proposed to design a biplanar micro-coil in this abstract. The main goal of this method is to increase the minimal distance between adjacent conductors of the coil. The planar surface can be discretized using a high-order triangular mesh. The magnetic field is calculated using the Biot-Savart law where the surface current density is expressed using a stream function and the surface integration is implemented using surface numerical integration based on the shape functions of the finite element.
