    Abstract : The discovery of metamaterials has led to major advances in different fields of physics including optics, microwave engineering and acoustics. Specific to theoretical electromagnetism, the introduction of metamaterials have led to the development of negative-index materials (NIMs) with simultaneous negative permittivity and negative permeability with backward-wave propagation.

  3. 2. Optical Studies ofNano-Structures in the BeetleCetonia Aurata

    University essay from Institutionen för fysik, kemi och biologi

    Author : Rizwana Shamim; [2009]
    Keywords : Cetonia aurata; Mueller-matrix ellipsometry; Helicoidal structures; Left-handed circularly polarized light;

    Abstract :       The main objective of this thesis is to study the polarization effects of the beetle Cetonia aurata using Mueller-matrix ellipsometry. The outer shell of the beetle consists of complex microstructures which control the polarization of the reflected light. It has metallic appearance which originates from helicoidal structures.

  4. 3. Metamaterial : A field magnitude dependent and frequency independent model

    University essay from Institutionen för teknik och byggd miljö

    Author : Mehdi Ardavan; [2008]
    Keywords : Metamaterials; Field Magnitude Dependent Model; Periodic Structures; FDTD;

    Abstract : In all attempts to analyze and realize Left-Handed materials, so far, most researchers have used the same idea of extracting only some or certain behaviors of Metamaterials from a set of unit cells gathered together in a designed order. Nevertheless meeting all criteria in order to consider a media as real double-negative material has never come true. READ MORE
