Surface wave cloaking using transformation optics

Recently, there has been an increasing interest in the study of manipulating surface waves from microwave to optical frequencies [1, 2], especially for the design of conformal antennas and devices in communications and radar applications [3]. Some of those designs based on metamaterials/metasufaces suffer from various problems, for example, they are highly dispersive, intrinsically narrow-band, lossy and highly anisotropy [4].
