Available in PDF, EPUB and Kindle. Book excerpt: An efficient and powerful computational method is presented to characterize a meta-material in terms of its specified electromagnetic properties. Using the periodicity of meta-materials, the Finite Element Methodology (FEM) is developed to estimate reflection and transmission through the meta-material structure for a normal plane wave incidence. For efficient computations of reflection and transmission through a meta-material over a wideband frequency range, a Finite Difference Time Domain (FDTD) approach is developed. Using the Nicholson-Ross method and Genetic Algorithms, a robust procedure to extract the electromagnetic properties of meta-materials from knowledge of their reflection and transmission coefficients is described. Numerical examples are presented to validate the approach.
