  1. 1. Numerical Simulations of Wave Propagation between a Left-Handed Material and a Right-Handed Material

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

    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. Model-based Study of Mixing- using Computational Fluid Dynamics and Experiments

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Victor Åberg; Ameer Shareef; [2018]
    Keywords : Fluid dynamics; Chemical engineering; Kemiteknik; Technology and Engineering;

    Abstract : Mixing in millimeter scale applications faces completely different challenges compared with the macro scale. A thorough understanding of the physics and mass conservation principles that are affecting the fluid dynamics, are therefore key for development and successful implementation of mixers, in an existing process.

  4. 3. Design, Fabrication and Validation of High-permittivity Low-loss Microwave Material for Biomedical Sensor

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Jasmin Gasi; [2018]
    Keywords : Biomedical; high dielectric constant; low loss dielectric; sensors; sin-tering; open ended coaxial probe; open ended circular waveguide; tita-nium dioxide;

    Abstract : Abstract The purpose of this task is to synthesize a dielectric substrate material through a sintering process, which can be used for non-invasive physiological sensor development. Low loss, high dielectric constant ceramic material is used. READ MORE

  5. 4. Identification, mapping and control of non-structure-bound materials

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : John Ahlberg; Christoffer Cruz Wolter Håkansson; [2014]
    Keywords : lagerstyrning; logistik; materialförsörjning; material; icke strukturbundet material; materialstruktur; struktur; flödeskartläggning; kartläggning; saab; saab aerostructures;

    Abstract : I Saab Aerostructures tillverkning av flygplansdelar, används icke strukturbundet material, det vill säga material som inte har en angiven kvantifierad förbrukning per tillverkad enhet eller material vars angivna kvantifierade förbrukning per tillverkad enhet inte stämmer överens med verklig förbrukning. Personal på inköpsavdelningen vet i vissa fall inte var ett specifikt icke strukturbundet material förbrukas, alltså vilka tillverkningsavdelningar eller flygplansdelar som förbrukar materialet.
