Abstract
Metamaterial are materials with electromagnetic properties not found in nature. In metamaterials, the structure of the material determines the electromagnetic properties and not the material of which it is made. Metamaterials, which may also be referred to as left handed materials, have opposite phase and group velocities, which create a backwards wave. The constitutive parameters, (the electric permittivity and magnetic permeability) of the left hand material are negative. The properties of these materials make them useful in a number of applications, including such things as invisible cloaking devices, lenses, antennas, and more. The focus of this thesis will be on antennas, particularly, small resonant CRLH composite right/left hand material antennas.
