Recently, it has been theoretically shown that anisotropic metamaterials with a near-zero index can flexibly control electromagnetic flux in the subwavelength scale. Here, by using two-dimensional transmission lines with lumped elements, we design and fabricate a type of anisotropic metamaterial with a near-zero permeability component. By further introducing spatial variations into the system, we experimentally realize the subwavelength flux manipulation in such a highly anisotropic environment, which is conducted via evanescent scattered waves. The experimental results agree well with the simulation. Our work verifies the feasibility of subwavelength flux manipulation in near-zero index materials. Copyright (C) EPLA, 2016
