Surface wave manipulation based on transformation optics: From design to manufacturing

In the last few years, much interest has grown in the control and manipulation of electromagnetic surface waves. The aim of this paper is to present a new design and manufacturing approach based on Transformation Optics. To validate the proposed design, an all-dielectric structure for surface wave propagation will be presented: the device shows good performance in terms of wide bandwidth, polarization independence, and easy-to-fabricate, with potential applications for antennas, sensors, imaging and telecommunications.
