In this chapter some experiments and applications of metamaterials in the microwave regime have been presented. Although metamaterials are composed of structures with finite periodicity, they can still be regarded as effective medium when the periodicity is far smaller than the wavelength. We discuss some interesting experiments such as the tunneling structure and the partial focusing phenomenon and investigate several applications like gradient index circuit and the Luneberg lens antenna. The simulation and experimental results show that metamaterials may have great potentials in the design of microwave devices and antennas.
