  1. 1. Numerical simulations of ultrafast dynamics in plasmonic nanostructures

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nils Henriksson; [2023]
    Keywords : Ultrafast nanophotonics; Three temperature model; Numerical simulations;

    Abstract : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. READ MORE

  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. Fabrication and Optimization of a Nanoplasmonic Chip for Diagnostics

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonas Segervald; [2019]
    Keywords : AFM; NIL; SPR; SERS; nanohole; nanohole array; nanoimprint lithography; physical vapor deposition; plasma treatment; plasmonic; plasmons; surface plasmon resonance; localized surface plasmon resonance; metal enhanced fluoresence; surface enhanced raman spectroscopy; transmittance; nanoplasmonic; signal enhancement;

    Abstract : To increase the survival rate from infectious- and noncommunicable diseases, reliable diagnostic during the preliminary stages of a disease onset is of vital importance. This is not trivial to achieve, a highly sensitive and selective detection system is needed for measuring the low concentrations of biomarkers available. 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. Design and Characterization of Plasmonic Absorbers Based on Gold Nano-spheres

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Jin Dai; [2012]
    Keywords : ;

    Abstract : Noble-metal-based nanostructures can exhibit strong localized plasmon resonance at optical frequency, which leads to efficient plasmonic light absorbers. Such an artificially engineered absorber can have potential applications in sensing, cancer diagnosis and therapy, and photovoltaic cells etc. READ MORE
