Wave scattering from cylindrical fluid inclusions in an elastic medium and determination of effective medium properties
… fluid-filled inclusion in an attenuating elastic medium. The scattering vs. angle results are shown for a laboratory experiment in which a single water-filled cylindrical inclusion is embedded in polypropylene. Four different radius-towavelength ratios of 1.9, 2.4, 8.8 and 11.0 were measured and …

Investigation of resonators loaded periodic structures
… under the fundamental limit of effective medium theory that the dimensions of the lattice are much smaller than the wavelength, we can treat the array of SRRs as bulk material and retrieve its effective parameters.

EXIT FROM THE MYOPIC IMPASSE: SOCIAL MOVEMENT STRATEGY IN THE AGE OF THE INTERNET
… an approach to communication studies known as medium theory, our study demonstrates that the use of Internet perpetuates certain, largely hidden temporal norms that are generally detrimental to the ability of contemporary activists to think historically, creatively and reflexively. This …

Neo-Raconteur: Allocating Southern-Gothic Symbolism into Design Media.
… the term Neo-Raconteur to convey my interest in medium theory to support the artistic custom of revealing cultural conventions for allocation into artistic genres. The term evolved from the French word "Raconteur," meaning: somebody who tells stories or anecdotes in an interesting or …

Assessment of dielectric models and their application to polymer matrix composites
… dielectric constant of the composite, effective medium theory based on Clausius-Mossoti equation was used. It was found that predictions for effective permittivity, based on this relation, correlate well with experimentally obtained results in the entire frequency range of investigation. To …

Thermal conductivity of fluids containing suspension of nanometer-sized particles
… based on classical Maxwell-Garnett effective medium theory. Although ethylene glycol containing gold nanoparticles produces significantly higher enhancement in thermal conductivity over those predicted by the Maxwell-Garnett theory, Fourier transform analysis indicates that the anomalous …

Statistical Physics of Semidilute Polymer Systems (And); Soft Billiard Systems
… of polymers in dilute solution. However, polymer theory in the semidilute regime is less sound. We first review RG results on statics, using the so-called direct method and employing the Edwards Hamiltonian. We present a careful RG account of arbitrarily polydisperse semidilute polymer solution, …

Hardwiring consumer desire: Publishing and promoting the online technocultural experience : a critical textual analysis of Wired magazine and its advertising, 1993-1996
… of the magazine form by drawing upon medium theory as articulated by Harold Innis and his successors Marshall McLuhan, Walter Ong, and Ronald Deibert. This approach is combined, secondly, with a historical comparative analysis of the American specialist lifestyle magazine as refracted …

Uniaxial optical phase change metamaterials
… are simulated on the basis of effective medium theory (EMT) and transfer matrix method (TMM). The findings in this paper demonstrate that broadband wavelength regions of high reflectance, high birefringence, and zero-crossing birefringence can be found and tuned as a function of material …

Percolation and homogenization theories for heterogeneous materials
… together with the generalized effective medium theory, we are able to directly predict the effective diffusivity and effective diffusional creep viscosity of heterogeneous grain boundary networks to a fairly accurate degree. Diffusion in composite solids exhibits different percolation …

The optical properties of bismuth nanowires
… two methods were developed. First, effective medium theory applied in reverse was used to deduce the dielectric function of materials smaller than the wavelength of light. Second, a technique to fabricate nanowires with diameters above 200nm was transfered into our laboratory.

Development of differential scheme micromechanics modeling framework for predictions of hot-mix asphalt (HMA) complex modulus and experimental validations
… based on the differential scheme effective medium theory has been developed and introduced herein. To verify and validate the prediction accuracy and applicability, a series of various asphalt-aggregate mixtures starting from the homogeneous asphalt binder phase up to a very highly packed …

An improved approach for quantifying the impact of geological uncertainty and modelling decisions on static and dynamic reservoir models - a case study from a giant fractured carbonate reservoir
… included in the reservoir model, using effective medium theory. The presence of fractures specifically improved the history matching quality for wells located close to the faults; these wells were very difficult to match in the past as fractures were not considered by the operator. This thesis …

Mechanics, shape, and programmability in soft matter systems: From fluid membranes to spring and droplet networks
… and I have constructed an effective medium (mean field) theory of an anisotropic, disordered spring network. We find that increasing the anisotropy increases the filament density required for a nonzero shear modulus (rigidity). We also conduct numerical simulations and find good …

First-principles and Many-Body Methods: Implementations and Applications to Study Spintronic Materials
… localization in DMSs with the typical-medium theory (TMT). Finally, we present a discussion about the investigation of the mechanism behind Ta2PdSe6 magnetoresistance. From a first-principles Wannier-function analysis, we find unambiguously the Mn valence in (Ga,Mn)N to be close to 2+ …
