  1. 1. Antenna Implants and Feasibility of Performance Limitations : AStudy of Radiation Efficiency on Electrically Small Antenna Implants with Finite Conductivity and Size

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

    Author : Erik Algarp; [2022]
    Keywords : Antennaimplant; Medical Implant CommunicationSystem; Electrically small antenna; Electric dipole; Magnetic dipole; Fundamental bounds; Performance limits; Radiation efficiency; Conductor loss; Antennimplant; Medical Implant Communication System; Elektriskt små antenner; Elektrisk dipol; Magnetisk dipol; Fundamentala begränsningar; Prestandagränser; Strålningseffektivitet; Metallförlust;

    Abstract : Antenna implants are used to establish a telemetry link to enable wireless data transfer, suitable for telemedicine and other medical applications. Inbody environments with water-based tissues lead to severe power absorption, making signal strength and radiation efficiency challenging yet central performance aspects of antenna implants.

  3. 2. Design of Autonomous Underwater Vehicle’s (AUV) Antenna System

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

    Author : Chengzhuang Zhou; [2021]
    Keywords : AUV Antenna; Printed Dipole Antenna; Broadband Antenna; AUV antenna; Printed dipole antenna; Broadband antenna;

    Abstract : The ocean symbolizes mystery, passion, and power. However, most of the ocean, about 80 %, is unknown to humans. AUVs (Autonomous Underwater Vehicles) provide a platform where terrain mapping, the biodiversity, and the resource survey of the ocean become accessible. READ MORE

  5. 4. Design and Simulation of Terahertz Antenna for Spintronic Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Nils Eivarsson; Malin Bohman; Emil Grosfilley; Axel Lundberg; [2020]
    Keywords : spintronics; terahertz; THz; antenna; simulation; COMSOL multiphysics;

    Abstract : Spintronics is a spin-electronic field where the electron spinangular momentum, in conjunction with charge, is used to read andwrite information in magnetic sensors and logic circuits, e.g. hard disk drive (HDD), magnetic random access memory (MRAM) and broadband TeraHertz (THz) emitters.

  6. 5. PARTON SHOWER UNCERTAINTIES ON THE TOP MASS

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Hristina Georgieva Hristova; [2019]
    Keywords : top quark mass; uncertainty; Lund Monte Carlo; Pythia; Physics and Astronomy;

    Abstract : The non-Abelian QCD nature allows for pp collisions to contain gluon emissions off quarks as well as gluon branchings into further gluons — a structure that can be described by the parton shower model. In this project we present the results of the impact the shower has on the reconstruction of the W-boson and top quark masses using Pythia, the Lund Monte Carlo event generator. READ MORE
