  1. 1. Investigation of Wide Band mm-Wave Radome

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Shreyasi Bhowmik; [2017]
    Keywords : ;

    Abstract : “Radome” is a necessary shield for any type of antenna. Itsshape, thickness, mechanical and electrical properties defineits application. This thesis mainly revolves around thetechniques, used for radome analysis in W-band with thehelp of electromagnetic solvers of High Frequency StructureSimulator (HFSS) and CST Microwave Studio.

  2. 2. Material Characterization by Millimeter-Wave Techniques

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

    Author : Leonard Andersson; [2016]
    Keywords : Material Characterization; time domain; frequency domain; reflection; transmission; free space; permittivity; conductivity; PMMA; Silicon; Measurement; Technology and Engineering;

    Abstract : This master thesis investigates material characterization by reflection and transmission of electromagnetic waves in the 40-60 GHz band (millimeter-wave spectrum) for different materials. The free-space measurement method is a fast, efficient and non-destructive way of examining a material and is being researched by both academics and industries. READ MORE

  3. 3. The kaon electromagnetic mass difference in AdS/QCD

    University essay from Lunds universitet/Teoretisk partikelfysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Jack Borthwick; [2016]
    Keywords : particle physics; AdS QCD; AdS CFT; kaon; electromagnetic mass difference; quantum field theory; Physics and Astronomy;

    Abstract : In this thesis, a holographic model for quantum chromodynamics (QCD) is used to estimate the electromagnetic contribution to the kaon mass difference. The principal ideas of the model are inspired by the AdS/CFT correspondence, which is believed to be exact. READ MORE

  4. 4. Updating bounds on the low-energy constants of Chiral Perturbation Theory from exact bounds on amplitudes

    University essay from Lunds universitet/Teoretisk partikelfysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Benjamin Alvarez; [2016]
    Keywords : Coupling constants; meson-meson scattering; Chiral perturbation theory; constraints.; Physics and Astronomy;

    Abstract : Chiral perturbation theory is an efficient effective theory to describe meson-meson scattering at low energy. An effective theory naturally introduces low energy constants and they are used, for example, to solve the ultraviolet divergences. READ MORE

  5. 5. Conservation laws in kinetic theory for spin-1/2 particles

    University essay from Umeå universitet/Institutionen för fysik

    Author : Linnéa Gräns Samuelsson; [2015]
    Keywords : plasma; quantum mechanics; conservation; momentum; angular momentum; quantum plasma; kinetic theory; spin;

    Abstract : In this thesis a kinetic theory for spin-1/2 particles is given a brief overview, focusing on the derivation of an evolution equation for the quasiprobability distribution function used in the theory to describe certain types of quantum plasma. The current theory is expanded upon by exploring conservation laws. READ MORE
