Abstract
The applicability of coordinate transformation methods are investigated for surface structures. It is shown that in-surface transformation implementations cannot perform the full range of applications achieved with volume media. Anisotropic impedance surfaces are used to split a surface wave beam and then recombine it in phase. An interior region is cloaked from the incident surface beam so that minimal energy enters. The beam shifting and combining is performed by using a linear coordinate transformation method.
