Artificial Materials by Olivier Vanbesien(auth.)

By Olivier Vanbesien(auth.)

This e-book addresses synthetic fabrics together with photonic crystals (PC) and metamaterials (MM).

The first half is dedicated to layout strategies: detrimental permeability and permittivity for detrimental refraction, periodic constructions, transformation optics.

The moment half matters workstation and MM in cease band regime: from cavities, publications to excessive impedance surfaces. irregular refraction, under one and unfavourable, in notebook and MM are studied in a 3rd half, addressing super-focusing and cloaking.

Applications for telecommunications, lasers and imaging platforms also are explored.

As we have seen through these two approaches – combined lattices and imbricated lattices – the degrees of freedom of conception for these structures are large.

If the geometric constraint is relaxed here, it is transferred to the building material. Very high permittivity levels can be found in ferroelectrics, for example, but the increase in targeted operating frequencies remains problematic as soon as we wish to go beyond the terahertz level, due not only to the intrinsic loss of the materials but also to the systematically decreasing permittivity values! 12.
