  1. 1. Establishing High-Temperature Models for Leakage Current in Gated Lateral Bipolar Junction Transistors

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Jimmy Atterstig; [2024]
    Nyckelord :Electronics; leakage current; brokaw bandgap; semiconductor physics; gauss-newton;

    Sammanfattning : Power-efficient circuits are a vital step in moving towards a greener future. Battery life can get substantially improved by decreasing the amount of power a circuit needs. Lower power also leads to less excess heat generated. LÄS MER

  3. 2. THE COUPLING OF A DOUBLE QUANTUM DOT TO MICROWAVE PHOTONS

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Mohamed Abrash; [2023]
    Nyckelord :Quantum computing; Qubit; Double quantum dot DQD ; Microwave resonator; Quantum integrated circuits; Sweet spots; Hybrid quantum circuits.; Physics and Astronomy;

    Sammanfattning : In this study, we derive a mathematical description of a double quantum dot (DQD) embedded in a microwave resonator starting from classical electrostatics. DQDs are a promising platform for building quantum computers and have important applications in quantum sensing and the study of light-matter interactions. LÄS MER

  4. 3. Microwave curing of composite material

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Arief Budi Sanjaya; [2023]
    Nyckelord :microwave curing; cured sample; uncured sample; numerical model; contact heating.; mikrovågshärdning; härdat prov; ohärdat prov; numerisk modell; kontaktuppvärmning.;

    Sammanfattning : Microwave curing has become a trend in composite processing due to its efficiency in energy consumption compared to the traditional curing method. However, as commonly found in every composite processing, controlling the microwave curing process remains challenging. The most feasible control method is to build a numerical model. LÄS MER

  5. 4. Modelling and Optimisation of Relativistic Magnetron with Transparent Cathode : Applications for High-Power Microwaves

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :David Sawert; [2023]
    Nyckelord :Relativistic Magnetron; RM; High-Power Microwaves; HPM; Particle-in-Cell; PIC; MAGIC3D; TE11;

    Sammanfattning : This thesis aimed to investigate the relativistic magnetron (RM), which is a high-power microwave (HPM) source. Since the RM can generate high-intensity microwave radiation, it can be used as a pulsed electromagnetic weapon to target electronic systems in different objects, such as drones, missiles, or vehicles.

  7. 5. Simulation of Microwave Heating of Healthy and Cancerous Human Tissue With Gold Nanoparticles

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hampus Carlens; Mika Söderström; [2022]
    Nyckelord :Gold nanoparticle GNP ; Electrophoretic resonance; Dispersive permittivity; Cancer treatment; Waveguide; Radiotherapy; Graded material.;

    Sammanfattning : With a great need for new and better cancer treatments, microwaves and gold nanoparticles (GNPs) are increasingly being suggested to be used in radiotherapy. In thisreport, the authors present an investigation of how human tissue,both malignant and healthy, behaves under microwave radiation. LÄS MER
