Topology Optimization for Electromagnetics: A Survey

The development of technologies for the additive manufacturing, in particular metallic materials, is offering possibility producing parts with complex geometries. This opens up to using topological optimization methods design electromagnetic devices. Hence, a wide variety approaches, originally developed solid mechanics, have recently become attractive also field electromagnetics. general distinction between gradient-based and gradient-free drives structure paper, latter becoming particularly last years due concepts artificial neural networks. aim this paper twofold. On one hand, aims at summarizing describing state-of-art on topology techniques while other it showing how methodologies non-electromagnetic framework (e.g., mechanics field) can be applied Discussions comparisons are both supported by theoretical aspects numerical results.
