  1. 11. "Resonance frequency, Q-factor, coupling of a cylindrical cavity and the effect on graphite from an alternating electric field".

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Jakob Gölén; Simon Persson; [2021]
    Keywords : Q-factor; Resonance frequency; Cavity; Microwaves; Heating; Q-faktor; Resonansfrekvens; Kavitet; Mikrovågor; Uppvärmning;

    Abstract : The purpose of this project was to investigate a cylindrical cavity resonator and use microwaves to heat up a material in the cavity. This was done by measuring the Q-factor and the resonance frequency of the cavity, both with and without material inside. READ MORE

  3. 12. Model verification and common mode current analysis of grid connected three phase two level converters

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Simon Lindvall; Richard Haraldsson; [2021]
    Keywords : active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

    Abstract : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. READ MORE

  4. 13. Quartic Higgs self-coupling at a 100 TeV pp collider

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Sebastian Grabowski; [2021]
    Keywords : Quartic Higgs self-coupling; Triple Higgs production; Future Circular Collider; FCC; MadGraph; MadAnalysis; Events selection; selection strategy; Physics and Astronomy;

    Abstract : We present a parton-level phenomenological study of triple-Higgs production at leading order in proton-proton collisions at a center-of-mass energy of 100 TeV with an integrated luminosity of 30 ab^-1. This study aims to estimate the prospects for measuring the signal hhh production observable at the Future Circular Collider. READ MORE

  5. 14. Searching for Dark Photons with Jet

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Ashar Ahmed Kamal; [2020]
    Keywords : light dark matter; jet substructure; Physics and Astronomy;

    Abstract : Dark matter is the greatest mystery of modern particle physics and cosmology. Although an overwhelming amount of observational cosmological evidence has pointed towards a dark sector, only its gravitational effect has been experimentally confirmed. READ MORE

  6. 15. Communication Channel Measurement and Modeling for Inductive Wireless Power Transfer

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Love Rosén; [2020]
    Keywords : Wireless power transfer; WPT; Qi Specification; Inductive coupling; Wireless charging; Channel modeling; Technology and Engineering;

    Abstract : Wireless Power Transfer (WPT) technology has experienced phenomenal success in the application of wireless charging of smartphones. With the Qi Specification becoming the dominant standard, wireless charging's convenience goes beyond cable-free charging to facilitate interoperability between chargers and devices from different vendors.
