1. 16. 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. 17. Building A Fixed Wing Autonomous UAV

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

   Author : Erik Barsby; Casper Augustsson Savinov; [2022]
   Keywords : fixed wing; bachelor thesis; KTH; Ardupilot; autopilot; electric propulsion; UAV; autonomous.;

   Abstract : The goal of this bachelor thesis has been to evaluate and test the available open source software and commercial hardwarefor potential later use as the electrical system in the ALPHAUAV. ALPHA is a student project, with the goal of building an autonomous drone capable of high altitude, long-endurance missions to gather data from electromagnetic phenomena in the atmosphere. READ MORE

4. 18. High-Performance Beamforming for Radar Technology : A Comparative Study of GPU Beamforming Algorithms

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

   Author : Oscar Lindgren; [2022]
   Keywords : Accelerated signal processing software; Beamforming; Electronic warfare; Electromagnetic waves; Emitter identification; Radar technology; Accelererad signalbehandlingsmjukvara; Beamforming; Elektronisk krigsföring; Elektromagnetiska vågor; Sändaridentifikation; Radarteknologi;

   Abstract : Radar technology is widely used in today´s society, whether it is the localisation and identification of aircraft in air traffic control systems, ships in harbour management systems, or the weather forecast presented on the news. In military applications, such as in fighter jets or missile lock-on systems, the speed at which the radar processes incoming data is essential to ensure a successful outcome. READ MORE

5. 19. Evaporation Duct Modelling for a Wave-Propagation Simulator

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Oscar Eklund; [2022]
   Keywords : evaporation; duct; height; monin; obukhov; mos; surface; layer; ssft; byc; pj; businger; dyer; beljaars; holtslag; cheng; brutsaert; sheba;

   Abstract : Long-range communication proves to be a challenge due to the Earth’s curvature, since electromagnetic waves propagate away from the Earth’s surface in a free atmosphere. A possible solution to beyond line-of-sight communication is the atmospheric phenomenon known as the evaporation duct. READ MORE

6. 20. Electrodynamic field at spatial infinity

   University essay from KTH/Fysik

   Author : Jakob Myhrman; [2022]
   Keywords : Spatial infinity; Conformal rescaling; Minkowski space; Penrose Diagram; Einstein universe; Newman-Penrose formalism; Sigma-process; Resolution of singularities; Maxwell s equations; Cylinder at spatial infinity; Rumslig oändlighet; Konform omskalning; Minkowski rummet; Penrose Diagram; Einsteins universum; Newman-Penrose formalismen; Sigma-processen; Singularitetupplösning; Maxwells ekvationer; Cylindern vid rumslig oändlighet;

   Abstract : The treatment of spatial infinity is one of the remaining major open problems in the theory of isolated self-gravitating systems. Especially when one wants to model scattering of gravitational radiation in spacetime. In this thesis the conformal theory is used to study simple electromagnetic fields, close to spatial infinity.
