Upscaling: Effective Medium Theory, Numerical Methods and the Fractal Dream. Effective-medium theory (EMT) is a powerful tool for de-scribing the radiative properties of complex heteroge-neous media. More precisely, EMT permits one to identify the average field (or coherent field) propagating inside a random medium, obtained by generating several realiza-tions of the random process, to the field propagating in- side a homogeneous medium with an effective permittiv. This approach also leads naturally into a treatment of effective‐medium theory and the description of the dielectric response of heterogeneous materials. Discover the world's research

We also assume that there are no source terms. We do not know of possible processes which could explain similarly the hypothetical fractality of other objects, nonetheless we suggest that further investigations should be conducted to seek out physical processes in the other cases. Global-local approaches call for global fine scale flow simulations and then local fine scale flow simulations. The calculation of the generalized susceptibility v which can be elastic modulus, permeability, etc. A simple MATLAB calculator using this formula is as follows. The focus then becomes accountability for pore and crack effects on elastic moduli.Keywords: effective medium theory, wire media, circuit model (Some figures may appear in colour only in the online journal) 1. Introduction Electromagnetic metamaterials are artificial materials that are engineered to affect electromagnetic waves, and hence show some properties that cannot be found in nature. In order to achieve these unconventional desired properties, these mate-rials are. effective medium theory; Maxwell-Garnett 1. Introduction Mesoscopically structured crystals, or mesocrystals, are highly ordered nanoparticle superstructures, showing organisation of nanocrystals in a crystallographic register [1,2]. Mesocrystals composed of optical materials can significantly extend the range of material properties available for optical devises and applications. Optical.
