  1. 1. A Travelling Wave Slot Array based on a Double-Layer Lens for 77 GHz Automotive Radar

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

    Author : Ashray Ugle; [2023]
    Keywords : Automotive radar; Double-layer lens; Gap waveguide technology; Waveguide slot; Antenna array; Lens-beamforming.; Bilradar; Dubbelskiktslins; Gap-vågledarteknik; Waveguide-kortplats; Antennuppsättning; Lens-beamforming.;

    Abstract : Automotive radars have gained considerable interest in recent years for applications of road safety for vulnerable road users. The use of multipleinput and multiple-output (MIMO) technology in automotive radar has helped in realising a virtual aperture greater than the physical aperture of the antenna which has reduced the size of the overall radar module.

  3. 2. Simulation of Microwave Heating of Healthy and Cancerous Human Tissue With Gold Nanoparticles

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

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

    Abstract : 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. READ MORE

  4. 3. A Comparison Between Applied Square and Ring CSRR on SIW Using the HOM Method

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

    Author : Carl Nordengren; Johan Bellbrant; [2022]
    Keywords : Split-ring resonators; bandgap-filter; higher order modes method; substrate integrated waveguide; periodic structures;

    Abstract : The rise of connected devices and the internet of things has increased the need for systems capable of transmitting high frequency signals wirelessly. An important part of these systems are the filters. Filters remove signals within unwanted frequency ranges. These filters can be implemented using e. READ MORE

  5. 4. Femtosecond-laser Written Integrated Optical Devices for Quantum Circuits

    University essay from KTH/Tillämpad fysik

    Author : Ang Chen; [2022]
    Keywords : Quantum optics; femtosecond-laser waveguide writing; integrated quantum photonics; photonic circuits; quantum technology.; Kvantoptik; femtosekundlaservågledarskrivning; integrerad kvantfotonik; fotonikkretsar; kvantteknologi.;

    Abstract : Integrated quantum photonic circuits have gained increasing interest in the field of quantum information, due to their compactness, the intrinsic stability and the potential scalability. Photons are the promising candidate for quantum information processing. READ MORE

  6. 5. Particle Simulation and Optimization of a Relativistic Magnetron for HPM Applications

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Wilhelm Thunberg; [2022]
    Keywords : Relativistic Magnetron; FOI Magnetron; TE11; HPM; High Power Microwaves; Particle in cell; MAgic3d;

    Abstract : A relativistic magnetron (RM) is a high-power microwave (HPM) source. The main objective of the RM is to generate directed electromagnetic pulses with high power, which can be used in e.g. HPM weapons and for electromagnetic compatibility testing. READ MORE
