  1. 6. Single-Layer Metamaterial Absorber for Radar Application

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Motasim Ahmed; [2016]
    Keywords : Metamaterials Absorber;

    Abstract : In the radar systems, the crosstalk or antenna-to-antenna interference between the radar antennas is useful in some cases. However in some application the received signal is too weak such as wall crack detection and it might affect the accuracy of the radar system. READ MORE

  3. 7. Self-Assembly and Electrical Conductivity of Colloids

    University essay from Uppsala universitet/Materialfysik

    Author : Pier Silvio Tibaldi; [2015]
    Keywords : colloids; self-assembly; electrical conductivity;

    Abstract : Self-assembly is an astonishing phenomenon at the base of organized structures’ formation from disordered systems. It occurs in nature from atomic and molecular lengths to galactic distances. Nowadays self-assembly of colloidal solutions can be used to fabricate photonic crystals and metamaterials. READ MORE

  4. 8. Developing a Compact Microwave Filter Using Metamaterials

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Jia Pengle; [2013]
    Keywords : ;

    Abstract : As communication services are growing, especially for keeping communication on high speed traffic, more efficient use of the available electromagnetic radio spectrum is required. In order to achieve this aim on communication spectrum, filters are required to be steeper. READ MORE

  5. 9. 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

  6. 10. Studies of Nanostructured Layers with UV-VIS Spectroscopic Ellipsometry

    University essay from Institutionen för fysik, kemi och biologi

    Author : Tijs Mocking; [2008]
    Keywords : ;

    Abstract : In this report a model analysis is presented for three different nanostructured layers: silicon nanotips (SiNTs), gold nanosandwiches and Split Ring Resonators (SRR). The last two materials are metamaterials and both may show a negative refraction index. READ MORE
