    Author : Balwan Rana; [2021]
    Keywords : Negative-Index Material; NIM; Positive-Index Material; RHM; Backward- Wave Propagation; Step-Index Interface; Graded-Index Interface; Left-Handed Material; LHM; Right-Handed Material; RHM; Analytical Solution; Validation; Negativt-Index Material; NIM; Positivt-Index Material; PIM; Bakåtvåg-utbredning; Steg-Index Gränssnitt; Gradering-Index Gränssnitt; Vänsterhänt Material; LHM; Högerhänt Material; RHM; Analytisk Lösning; Validering;

    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. Electromagnetic Phase Engineering With Metamaterials

    University essay from KTH/Tillämpad fysik

    Author : Olof Sjödin; [2021]
    Keywords : Applied Physics; Electromagnetism; Metamaterials; MIM; Plasmonics; FEM; Reflector design; Phase engineering; Tillämpad fysik; Elektromagnetism; Metamaterial; MIM; Plasmonics; FEM; Reflektor design; Fasdesign;

    Abstract : Metamaterials are artificially designed materials with desired electromagneticresponses for advanced wave manipulation. Their key constituent is often somenoble metal, thanks to its well localized plasmonic effects with highextinction cross section. READ MORE

  4. 3. 3D Printing a Maxwell Fish Eye Lens With Periodic Structures

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Valentine Lin; Tarek Sayed Hamad; [2019]
    Keywords : Maxwell fish eye lens; dielectric lens antenna; metamaterial; periodic structure; 3D printed lenses.;

    Abstract : With the rise of high frequency communication systems such as 5G, new types of antennas has to be developed in order to meet the new requirements. In recent years, lens antennas made of periodic structures has been shown to have desirable performance when increasing operational frequency without increasing the size of the antennas. READ MORE

  5. 4. Towards a tunable nanometer thick flat lens

    University essay from Uppsala universitet/Materialfysik

    Author : Hugo Laurell; Johan Hillborg; [2018]
    Keywords : Metamaterial; COMSOL; Fano resonances; Surface plasmon polariton; Localized surface plasmons; Nanophotonics;

    Abstract : This report examines the cross sections of silver microresonators subjected to an incident light with different polarization. The microresonators had different geometries with and without broken symmetries. READ MORE

  6. 5. Study of Two-dimensional Kirigami in Different Materials

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Joseph Noble; [2018]
    Keywords : FEM; Material Selection; Metamaterial; Stiffness Tuning; Venepuncture; FEM; materialval; metamaterial; styvhetsanpassning; venpunktion;

    Abstract : De mekaniska egenskaperna hos ett tvådimensionellt material kan ändras med hjälp av Kirigami, som är en japansk klippkonst i papper. Material där man med geometriförändringar ändrar materialegenskaperna kallas metamaterial. READ MORE
