This ebook addresses synthetic fabrics together with photonic crystals (PC) and metamaterials (MM).
The first half is dedicated to layout ideas: unfavorable permeability and permittivity for detrimental refraction, periodic constructions, transformation optics.
The moment half issues computing device and MM in cease band regime: from cavities, publications to excessive impedance surfaces. irregular refraction, lower than one and destructive, in computing device and MM are studied in a 3rd half, addressing super-focusing and cloaking.
Applications for telecommunications, lasers and imaging structures also are explored.

The first Brillouin zone and the high-symmetry points Γ, X, K and M, are also listed. Let us remember that for the (triangular) square lattice, the zone delimited by points ΓXM (ΓMK) is called the 46 Artificial Materials irreducible Brillouin zone. Knowing the structure of the bands in this zone is sufficient to know all of the modes of propagation in the crystal. Among the other parameters that will define the dispersion characteristics, we can mention the shape of the unit particle in its unit cell and the filling factor that defines the percentage of material corresponding to the particle in relation to its matrix.

We will particularly focus on two-dimensional structures to help with understanding the key properties of photonic crystals for their use in band gaps and in pass bands. 2. 1. A few considerations about band gaps and pass bands The opening of a gap in a one-dimensional structure can be explained simply. Let us consider a periodic pile of dielectric plates of index n1 and n2, and of the same thickness, a/2. When the wavelength in the medium reaches λ = 2a, the reflections are in phase and can produce a stationary wave.
