ad Snapshots of the simulated magnetic fields for circular hybrid invisibility cloaks with various geometries and types of ZIMs under an incident TM plane wave from the left. a A ZIM layer composed of a double-zero medium with ε = μ = 0.001 embedded with a dove-shaped PEC scatterer. b A ZIM layer composed of a double-zero medium with ε = μ = 0.0001 and thickness dZIM = 0.005R. c A ZIM layer composed of a single-zero medium with ε = 0.0001 and thickness dZIM = 0.005R. d A ZIM layer composed of an anisotropic zero-index medium with ε = 0.0001 and thickness dZIM = 0.005R. The parameters and thicknesses (dMS = 0.005R) of the metasurfaces in (ad) are exactly the same
