  1. 1. A Novel and an Efficient Design of an Inverted F-Antenna for Bluetooth Low Energy Communications

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Amer Khatib; [2019]
    Nyckelord :Antenna; Communication; design; testing; Wireless communications; bluetooth.;

    Sammanfattning : Constantly, antenna plays an important role in expanding the wireless communication systems in different technology applications for example, but not limited to, IoT communications and automotive radar systems. On the other hand, the Bluetooth-Low-Energy (BLE) benefits different sorts of applications, as it offers (i) a very low power consumption, (ii) a very fast data transfer, (iii) and an inexpensive/efficient solution as well.

  2. 2. Transient Dynamics and Core Tunneling in Vertical Spin-Vortex Pairs

    Master-uppsats, KTH/Nanostrukturfysik

    Författare :Milton Persson; [2019]
    Nyckelord :Spin-vortex; ultra fast vortex dynamics; milli-Kelvin temperatures; macroscopic quantum tunneling; Spinnvirvel; ultrasnabb virveldynamik; milli-Kelvin temperaturer; makroskopisk kvanttunnling;

    Sammanfattning : Spin-vortices in vertically spaced pairs of thin elliptical Permalloy nanoparticles are investigated. The two vortex cores with parallel out-of-plane magnetization exhibit a strong monopole-like attraction through the spacer much thinner than the core length, thus forming a bound core-core pair.

  3. 3. A Study of Abelian Dualities in 2+1 Dimensions

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Xiaoyi Jing; [2019]
    Nyckelord :Chern-Simons; Duality; IR Fixed Point; Monopole;

    Sammanfattning : It is well-known that in 2 + 1 dimensions the flux attachment transmutes the statistics of a particle.The aim of this master thesis is to study the dualities between bosons and fermions induced by Abeliantopological gauge fields in 2 + 1 dimensions. LÄS MER

  5. 5. Electromagnetic Duality in SO(3) Yang-Mills Theory : Bachelor Thesis

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Jim Lundin; [2018]
    Nyckelord :Montonen-Olive conjecture; BPS states; t Hooft-Polyakov monopole; Witten effect; SL 2; Z invariance;

    Sammanfattning : We introduce the historical context and motivation for the search for magnetic monopoles or monopole-like objects. Beginning the theoretical part we investigate the properties of groups as they relate to symmetries in physical theories. LÄS MER
