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

摘要

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.
