  1. 1. Geometry Dependent Optimal Bounds of Absorption and Scattering Cross-section for Small Nanoparticles

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Md Shabbir Hossain Khan; [2022]
    Keywords : Scattering; Absorption; Nanoparticle; Cross-section; Mie; Electromagnetic; FDTD; dipole; Wavenumber.;

    Abstract : Light-matter interaction in particles of subwavelength size mostly depends on the size, shape, composition of the particles and relies on the properties of incident light. Henceforth, resonant behavior of light can be effectively controlled by changing the aforesaid geometrical parameters. READ MORE

  3. 2. Investigating the use of Semiconductor Nanowires for Neural Networks

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Alfredo Serafini; [2022]
    Keywords : FDTD method and simulation; optical broadcasting neural network; optical communication of nanowires; sub-wavelength absorption.; Physics and Astronomy;

    Abstract : In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonomous drones. READ MORE

  4. 3. 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

  5. 4. 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.

  6. 5. 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. READ MORE
