  1. 1. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance

    University essay from KTH/Tillämpad fysik

    Author : Daniele Lopriore; [2022]
    Keywords : Quantum technology; microwave engineering; nanofabrication; parametric amplifiers; multimode entanglement; kinetic inductance; Kvantteknologi; mikrovågsteknik; nanotillverkning; parametriska förstärkare; multimodentrassling; kinetisk induktans;

    Abstract : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. READ MORE

    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.

  4. 3. Out-of-plane Ferromagnetic Resonance (FMR) measurements on magnetic nanoparticle dispersions for biomedical sensor applications

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Markus Back; [2020]
    Keywords : Ferromagnetic; magnetic; resonance; FMR; EPR; nanoparticle; microwave; coplanar; waveguide; cavity; s-parameter; gilbert; damping; gyromagnetic; liquid; biosensor; landau; lifshits; spin; polymer; composites; engineering physics; teknisk fysik; magnetism; ferromagnetisk; vågledare; resonans; mikrovågsteknik; nanopartiklar;

    Abstract : In this master work, we investigated the feasibility of a magnetic resonance measurement technique using magnetic nanoparticle dispersions in both liquid and solid form. The implementation is realised as a coplanar waveguide operating in the frequency range of 0.5 - 20 GHz and an electromagnet producing a static magnetic field of strength up to 1. READ MORE

  5. 4. Upptag av tungmetaller i maskros (Taraxacum officinale) : förekomst och påverkan av bly och kadmium vid odling i Malmö stad

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Emma Lundström; [2017]
    Keywords : tungmetaller; upptag; urban odling; växter; skyddsmekanismer; kontaminering;

    Abstract : För att få en uppfattning av innehållet av tungmetall i urbant odlade grödor analyserades halterna av bly och kadmium i maskrosor (Taraxacum officinale) och jordprov från i Malmö stad. Provpunkterna fördelades brett i staden och kategoriserades efter markanvändning och grad av förorening. READ MORE
