The homogeneous and inhomogeneous field in ZIMs.
(a) The schematic plot of a cylinder of ZIMs placed in air. (b) The schematic plot of a cavity structure with ZIMs placed in air. The core medium is air as well. (c) The real part of electric field for a line source inserted in the ZIM cylinder. (d) The real part of electric field for a line source inserted in the cavity of ZIMs, where dipole mode is excited. For (c) and (d), the effective permittivity and permeability of MNZ are ε2 = 1 and μ2 = 10−3 respectively and for MNZ shell, its inner and outer radii are R1 = 15 mm and R2 = 30 mm.
