  1. 6. Characterization of monkey fat tissues : To assist their viability for fat intra-body communication as an early step of non-human primate testing (NHP)

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Qsai Alyounes; Alkari Razan; [2022]
    Keywords : Fat-IBC; Monkey tissues; Phantoms; Network analyzer; Dielectric proporties;

    Abstract : Fat intra-body communication is a newly proven concept that is built on using human fat tissues as a communication channel for electromagnetic waves inside the body. This allows for two implanted external devices to connect through an intra-body closed-loop communication channel. READ MORE

  3. 7. Micro- / Meso- Scale Dielectric Strength Testing of Fibre Composites

    University essay from Umeå universitet/Institutionen för fysik

    Author : Johannes Fernberg; [2022]
    Keywords : Dielectric strength; composite; GFRP; glassfibre; composite microstructure; FEA; electric breakdown; single fibre;

    Abstract : Glass fibre composites are common materials used in high voltage applications as insulating materials that provide good structural integrity. The aim of this thesis is to develop a method of studying the failure in such materials by measuring the dielectric strength on micro- and meso- scale samples, consisting of single fibre filaments and fibre bundles respectively embedded in epoxy resin.

  4. 8. Magnetic and Dielectric Design of Auxiliary Power Supply for HVDC Applications : A high-frequency transformer with high power transfer capability and high voltage electrical insulation

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

    Author : Henrik Johansson; [2022]
    Keywords : Auxiliary Power Supply; HVDC; Inductive Power Supply; High Voltage Insulation; High-Frequency Transformer; Hjälpkraftsförsörjning; HVDC; Induktiv Kraftförsörjning; Högspänningsisolation; Högfrekvenstransformator;

    Abstract : It is anticipated that massive amounts of energy will be transferred long distances via High-Voltage Direct Current (HVDC) links in the future and the prospect of having meshed HVDC grids is envisioned, for example the European super grid. Such a power system would benefit greatly if HVDC circuit breakers could reliably clear faults within the HVDC network. READ MORE

  5. 9. Anti-Reflective Coatings for 3D Printed Quasi-Optical Lenses: Experiments, Simulations, Verification, and Optimization

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Christina Ashok; [2022]
    Keywords : ;

    Abstract : This thesis aims to see how well anti-reflective coatings created for dense material millimeter wave integrated lens work and to validate observations using electromagnetic simulation. The dielectric material was chosen for lens fabrication because it allows for high power transfer capability via the lens and allows the production of affordable and compact-size lenses. READ MORE

  6. 10. Development Of Lung Phantoms for Detection Of Acute Respiratory Distress Syndrome

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Wassim Wahbeh; Youssef Hasan; [2022]
    Keywords : DARDS;

    Abstract : The goal of this project was to fabricate a deflated and an inflated phantom to replicate how the human lung tissues’ permittivity changes under a pathological condition for instance acute respiratory distress syndrome (ARDS). Furthermore, the lung phantom should be shaped like real human lungs. READ MORE
