Metamaterials are currently under development to reduce the size of high power antennas. These materials may also have applications in other high power, dielectric-loaded components, including nonlinear transmission lines. A new procedure has been developed at the University of Missouri-Columbia that produces a double-positive metamaterial by combining nickel-zinc ferrite powders with a dielectric...
A new research effort at the University of Missouri-Columbia aims to develop metamaterials for high power antennas and other microwave devices. In the past, size reduction of high power antennas has focused on the development of materials with a high relative permittivity. However, the authors propose that by controlling both the permittivity and permeability, it will be possible to significantly...
