Unit cell of the 2D anisotropic TL MTM.
Photograph of the proposed 2D experimental structure to demonstrate the cloak effect, where both the cloak shell and the background medium are represented by the LC MTMs networks.
Calculated effective constitutive parameters in the cloak domain and in the background medium in our demonstration experiment (a), (b), and (c); the corresponding TL parameters to implement them, respectively, (d), (e), and (f). Theoretical values of the lumped elements are shown in stair (blue) lines, and the values used in the experiment are shown in dotted (red) lines.
Voltage distribution snapshot simulated from ADS at 40.1 MHz (a) and the corresponding experimental result (b). Experimental voltage distribution snapshots taken at 32 MHz (c) and 24 MHz (d). The solid black lines define the calculation boundaries and separate the cloak (area between the inner two circles) with the background medium (area between the outer two circles) (unit: V).
