    Explorations of artificial materials for manipulating electromagnetic waves began at the end of the 19th century. Some of the earliest structures that may be considered metamaterials were studied by Jagadish Chandra Bose, who in researched substances with chiral properties. Karl Ferdinand Lindman studied wave interaction with metallic helices as artificial chiral media in the early.

Starting from equivalence theorem any composite metallic and dielectric structure can be analyzed by using SIE (Surface Integral Equation). Such integral equations are usually solved by MOM (Method Of Moments).

Most of the existing MOM methods for solving SIE are developed for BORs (Bodies Of Revolution). There are only few such methods that can handle structure of arbitrary shape.

In this book, we present an efficient and unified approach to the electromagnetic modeling of practically arbitrary composite metallic and dielectric structures in the frequency domain. This approach is based on the method of moments (MoM), a general technique for solving numerical problems of electromagnetic fields.

Modern design procedure of antennas, microwave components and EMC facilities usually includes full wave analysis of composite metallic and dielectric structures in frequency domain. One of the methods that can be used for such full wave analysis is method of moments (MoM) applied to surface integral equations (SIEs).

Similar to a conventional all-metal disc-loaded waveguide (model-4), the structure periodicity is the most effective parameter for tailoring the dispersion characteristics of the structure with dielectric discs between the metal discs (model-6), for the TE 01 and TE 02 modes, more for the latter.

The transparent metallic structure is composed of a stack of alternating layers of a metal and a dielectric material, such that the complex index of refraction alternates between a high and a low. 2D and Quasi-2D Composite and Nanocomposite Materials: Theory, Properties and Photonic Applications covers the theory, characterization and computational modeling of 2D composite materials and shows how they are used for the creation of materials for 3D structures.

Electromagnetic modeling of composite metallic and dielectric structures By Branko Kolundzija and Antonije R Djordjevic Topics: Engineering. of modeling extremely large scale composite materials (with up to 1 million strongly interacting metal or dielectric particles).

This capability is crucial in order to study the electromagnetic response of large scale inhomogeneous (fractal) films and bulk composites at critical concentrations (percolation). The developed numerical method is. In a lossless non-magnetic biaxial material, the three principal refractive indices are, a uniaxial material, it is common practice to write and, where and are the ordinary and extraordinary refractive indices, respectively.

Hyperbolic metamaterials are extremely anisotropic uniaxial electromagnetic materials, which behave like a metal in one direction and like a dielectric in the. By designing this structure, the electromagnetic properties can be tailored for potential applications in novel devices. Here, molecular dynamics of polymer matrices and nanocomposites is analyzed by parametric modeling of their dielectric spectra, supporting design of a composite with desired electromagnetic properties.

From the composite structure, we have proposed a new multi-layer structure with three layers (1, 3 and 5) display the same characteristic 60 fibres (TiF) with conductivity σ=*10 6 S/m, at mm radius dispersed in a dielectric layer (Si) a ɛ= with mm thick.

The three layers are separated via silicon (Si) at 1 mm thick, as shown. The capability of composite materials to shield electromagnetic fields is coherently associated with their dielectric properties in a wide frequency band.

The method of impedance spectroscopy allows one to connect the measured frequency characteristics with the physical structure of tested material and the alternations in the structure.

The MGA model can be used to calculate the frequency-dependent effective permittivity of composite structures with aligned cylindrical inclusions from their geometrical parameters [15,36,37]. The present study deals with aligned inclusions.

The new approach is based on. structures. The numerical modeling of the mixed-dielectric and metal-dielectric composites is carried out by deflning the unit cells having periodicity along the plane perpendicular to the direction of propagation.

They have alternating regions of high and low dielectric materials (Fig. 1) (3), designed to have an electromagnetic stop-band at a desired frequency and in a desired direction (4).

Multi-layer, metallo-dielectric structures (screens) have long been employed as electromagnetic band filters, either in transmission or in reflection modes.

Here we study the radiation energy not transmitted or reflected by these structures (trapped radiation, which is denoted—absorption).

The trapped radiation leads to hot surfaces. In these bi-layer screens, the top (front) screen is made. The present work aims at building up a full‐wave computational model of electromagnetic nondestructive testing of composite materials produced by stacking up dielectric slabs one over the other.

In each such dielectric slab, a periodic array of infinite cylindrical fibers is embedded. Abstract: Two types of generalized characteristic-mode (CM) formulations are proposed for the modal analysis of composite structures with arbitrarily metallic-dielectric combinations.

The contact-region modeling (CRM) technique is introduced to conveniently model an arbitrary composite electromagnetic (EM) structure as a combination of relatively simple single region. Moreover, a lower dielectric constant will be favored to restrict the impedance mismatch at the interface between air and surface samples and thus to restrict the electromagnetic wave reflectivity at this interface.

The composite material then provides a high absorption level: from 5 dB/cm at 4 GHz to 16 dB/cm at 18 GHz. Three dimensional composite The simple three-dimensional model of the composite material is created by a lossy metallic grid (copper grid).

The grid is made from the wire of the diameter mm. Cells of the grid are of the dimensions mm × mm. The grid is rotated for 45 degrees. The metallic grid is covered by the lossy dielectrics.

This work presents the results of computer modeling and experimental measurements of microwave transmission properties for one-dimensional periodic multi-layered photonic structures (PCs), composed of epoxy layers and composite layers filled with nanocarbon particles—multi-walled carbon nanotubes and graphite nanoplatelets.

The results show that the characteristics of observed photonic .Graphical abstract: A resistor–capacitor model could well describe the relationships between the structure and the dielectric properties, electromagnetic interference shielding and microwave-absorption of the composites in the frequency range of 2–18 GHz.
