Rapid design for metamaterials
Metamaterials are generally composed of sub-wavelength structures with designable geometries. The macroscopic properties of metamaterials are harnessed by engineering the geometric dimensions of the particles. During the past few years, designing metamaterials has become increasingly time-consuming due to the growing complexity of their electromagnetic properties and the complexity has been spurred by the arising interest in generating inhomogeneous and anisotropic metamaterials. Motivated by accelerating the design process for metamaterials with excellent accuracy, rapid design for metamaterials is introduced in this chapter. This method is based on full-wave simulation, S-parameter retrieval technique, and the effective medium theory for metamaterials. The rapid design algorithm for metamaterials is widely applicable to all particles with or without resonances from microwave to optical regime. Its efficiency is validated and demonstrated by a few examples. © Springer Science+Business Media, LLC 2010.
