Multi-Objective Optimisation of Metamaterial Antenna

Passive manipulation of radiation is key to many modern technologies for sensing and communication. While many techniques exist to design electromagnetic systems that perform a single desired function, the design of systems which are multi functional remains challenging. We have developed a versatile semi analytic framework for designing multi functional metamaterials to shape antenna radiation. To demonstrate the versatility of this method we design two devices: one which re shapes the radiation pattern of an emitter while also enhancing the efficiency, and one which beams radiation into different directions depending upon the polarisation of a driven element.
