Three-dimensional Topology Optimization of Planar Multilayer Busbar

This paper addresses the optimal design of three- dimensional planar multilayer busbar, through the general setting of topology optimization. The optimization problem is efficiently solved with a gradient-based mathematical program- ming algorithm, that exploits a harmonic adjoint variational formulation sensitivity analysis for the harmonic linear mag- netodynamic problem. This formulation can handle topology design variables defined on a finite element mesh
