Electromagnetic invisibility cloaks based on inverse design method

Inspired from the thoughts of forward-design cloaking techniques, invisibility cloaks with inverse designs have experience a period of remarkably fast development in the past few years. In this paper, we report an inverse design method of invisibility cloaks based on the Mie scattering theory with the adoption of the genetic algorithm. With the inverse design, an invisible dipole antenna is demonstrated experimentally and an omnidirectional spherical invisibility cloak design is proposed.
