Abstract:

Metamaterials are compound materials exhibiting electromagnetic properties not readily found in nature. Novel antennas, couplers, imaging systems and methods for the reduction of the radar cross-section based on these properties have been proposed in literature.  In this talk a systematic synthesis technique for metamaterials is presented. The foundation of this approach is that metamaterials consist of unit cells that are small compared to the wavelength. The topology of the unit cell's network representation can be derived from space-discretising schemes in 1D, 2D, and 3D.  Using this technique two novel isotropic 3D metamaterials are synthesised. Maximally-symmetric and planar physical realisations are proposed and verified by full-wave simulation and experiment, respectively.
