  1. 1. Antenna with medical applications for tumour cancer: hyperthermia function

    University essay from Högskolan i Gävle/Elektronik

    Author : Iñaki Abrego peris; [2017]
    Keywords : ;

    Abstract : The idea is to improve or help the treatments that exist in the market in the medical field. Treatments such as mammography or radiotherapy make use of X-rays. X-rays are electromagnetic radiation in a high frequency band, this type of electromagnetic is dangerous to health because ionizing radiation is used, ionized atoms interact with matter. READ MORE

  2. 2. 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.

  3. 3. Analysis of Force and Torque Harmonic Spectrum in an Induction Machine for Automotive NVH Purposes

    University essay from Chalmers tekniska högskola/Institutionen för energi och miljö

    Author : Inigo Garcia De Madinabeita; [2016]
    Keywords : induction; motor. drivetrain; NVH; automotive; electric; vehicle; mobility; noise;

    Abstract : Currently, hybrid and fully electric vehicles are being developed in a great varietyregarding topology, power and range. This requires a new methodology for NVH(Noise Vibration and Harshness) evaluation of potential problems early in the designphase. READ MORE

  4. 4. 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

  5. 5. 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
