Designing Materials with Desired Electromagnetic Properties
In this work, we suggest and demonstrate a robust method to tune the plasma frequencies of wire mediums. The method we suggest involves the use of two or more wire arrangements in the unit cell. By incorporating the method we suggested it is possible to tune the plasma frequencies of wire mediums effectively by use of lower metal densities. In addition, we study the effective permittivities and...
متن کاملElectromagnetic wave scattering by many small bodies and creating materials with a desired refraction coefficient
Electromagnetic wave scattering by many small particles is studied. An integral equation is derived for the self-consistent field E in a medium, obtained by embedding many small particles into a given region D. The derivation of this integral equation uses a lemma about convergence of certain sums. These sums are similar to Riemannian sums for the integral equation for E. Convergence of these s...
متن کاملPreparing materials with a desired refraction coefficient
A recipe is given for creating material with a desired refraction coefficient by embedding many small particles in a given material. To implement this recipe practically, some technological problems have to be solved. These problems are formulated. PACS 43.20.+g, 62.40.+d, 78.20.-e. MSC 35J10, 74J25, 81U40
متن کاملCreating materials with a desired refraction coefficient
A method is given for creating material with a desired refraction coefficient. The method consists of embedding into a material with known refraction coefficient many small particles of size a. The number of particles per unit volume around any point is prescribed, the distance between neighboring particles is O(a 2−κ 3 ) as a → 0, 0 < κ < 1 is a fixed parameter. The total number of the embedde...
متن کاملDesigning disordered hyperuniform two-phase materials with novel physical properties
Heterogeneous materials consisting of different phases are ideally suited to achieve a broad spectrum of desirable bulk physical properties by combining the best features of the constituents through the strategic spatial arrangement of the different phases. Disordered hyperuniform heterogeneous materials are new, exotic amorphous matter that behave like crystals in the manner in which they supp...
