Planar distributed full-tensor anisotropic metamaterials for cloaks of invisibility based on transformation electromagnetics are proposed. The proposed metamaterials are composed of nonresonant transmission lines and are advantageous in full control of the off-diagonal components of the permeability tensor as well as broadband and low-loss characteristics. The explicit design formulas for the metamaterials are given based on the equivalent circuit derived directly from Maxwell's equations. A carpet cloak of invisibility is designed and the validity of the design theory is confirmed by circuit simulations. In addition, the carpet cloak is implemented in microstrip line technology and its performance is demonstrated experimentally at microwave frequencies.
