An ongoing effort to reduce the size of high power antennas in the VHF and UHF bands investigates loading novel composite materials into the antenna structure. A previous effort developed high dielectric constant composites with a high dielectric strength for high power antennas. The current work aims to develop metamaterials with greater-than-unity values of relative permittivity and permeability...
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...
