We report a new type of planar metamaterial consisting of a pair of homogeneous parallel plates separated by a thin medium. Strong magnetic response and negative effective permeability are observed in the materials at wavelengths from 6.9 μm to 5.8 μm. The resonant wavelength and the value of the negative permeability can be tuned by varying the structure dimensions. Such planar metamaterials can be easily fabricated with mature thin film technology and are of great potential for device applications.
