  1. 1. Simulating Microwave Heating for Industrial Processes Using the Finite-Difference Time-Domain Method

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Dante Grenholm; Axel Nilsson; Linus Olofsson; Oskar Pettersson Löfstedt; [2022]
    Keywords : Microwave oven; Heating; Simulation; Mikrovågsugn; Uppvärmning; Simulering;

    Abstract : Microwave heating is an efficient way of heating compared to conventional industrial alternatives such as autoclaves, a type of pressure cooker commonly used for curing and sterilisation. One problem that limits the adoption of microwave ovens in industrial processes is uneven heating. READ MORE

  3. 2. Dielectric Response of SiC-based Stress Grading Material Used in Electrical Machines

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

    Author : Shilin Zhao; [2021]
    Keywords : Dielectric frequency response; End corona protection; Finite element method; High voltage rotating machines; Stator insulation; Dielektrisk frekvensrespons; Ändglimmskydd; Finita element metoden; Högspänningsmaskiner; Statorisolering;

    Abstract : High Voltage (HV) rotating machines are widely used in power generation and heavy industry companies. Silicon Carbide (SiC) material is used in the stress grading structure of HV electric machines because of its non-linear characteristic. READ MORE

  4. 3. Investigation of Hybrid Simulation Methods for Evaluation of EMF Exposure in Close Proximity of 5G Millimeter-Wave Base Stations

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

    Author : David Anguiano Sanjurjo; [2020]
    Keywords : 5G; base station; EMF exposure; hybrid simulation method; millimeter wave;

    Abstract : With the emergence of Fifth Generation (5G) mobile networks, the employment ofhigher frequencies in the millimeter-wave (mmWave) range and the realization of agreat number of beams in 5G radio base stations (RBS) make the electromagnetic (EM)simulation of RBS products very costly in terms of hardware and time requirements.In order to compute the electromagnetic field (EMF) exposure in close proximity of theRBS, more efficient simulation methods are required.

  5. 4. Simulating Low Frequency Reverberation in Rooms

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Mattias Svensson; [2020]
    Keywords : Low frequencies; Room acoustics; Finite Difference Time Domain method; FDTD.; Rumsakustik; låga frekvenser; Finite Difference Time Domain metoden; FDTD.;

    Abstract : The aim of this thesis was to make a practical tool for low frequency analysis in room acoustics.The need arises from Acad’s experience that their results from simulations using raytracing software deviate in the lower frequencies when compared to field measurements inrooms.

  6. 5. Multiple electromagnetic scattering by spheres using the T-matrix formulation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Marina Wallin; [2015]
    Keywords : T-matrix; Multiple scattering; RCS; FDTD; Electromagnetic scattering; Mie scattering;

    Abstract : Low observable technology is used in order to prevent detection, or to delay detection. Radar cross section is an important parameter in aircraft survivability since it measures how detectable an object is with radar. To find the radar cross section Maxwell's equations are solved numerically in the time-domain using a finite difference scheme. READ MORE
