  1. 1. Modeling wave behavior with linear wave theory

    University essay from Umeå universitet/Institutionen för fysik

    Author : Elsa Renström; [2024]
    Keywords : ;

    Abstract : This thesis aimed to look at the behaviours of the water beneath waves from a modeling and simulations point of view. We have investigated how to use Linear wave theory (LWT) to model the kinematic movements in water governed by free ocean waves. The model assumes the surface to consist of a superposition of sinusoidal waves. READ MORE

  3. 2. Oscillations in a complex sunspot: From theory to data

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Femke Kranenbarg; [2024]
    Keywords : ;

    Abstract : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

  4. 3. Localized and extended states in finite-sized mosaic Wannier-Stark lattices

    University essay from KTH/Tillämpad fysik

    Author : Emrah Tortumlu; [2023]
    Keywords : Applied Physics; Condensed matter physics; quantum technology; quantum nanophotonics; localization; mobility edge; phase transition; Tillämpad Fysik; Kondenserade materiens fysik; kvantteknologi; kvantnanofotonik; lokalisering; fasövergång;

    Abstract : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

  5. 4. Probabilistic Added Wave Resistance Predictions for Design of RoPax Ferries

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Jonathan Viinikka; [2023]
    Keywords : Added wave resistance in head waves; Roll-on Roll-off Passenger ferry; Probabilistic wave environment; Semi-empirical method; Adderat vågmotstånd i motsjö; Roll-on Roll-off Passagerar Fartyg; Probabilistiska vågförhållanden; Semiempiriska beräkningsmethoder;

    Abstract : This thesis investigates reasons for significant uncertainties in added wave resistance predictionsand how wave conditions can potentially affect the design of RoPax ferries. The objectiveis to find a suitable prediction method of added wave resistance for the RoPax ferry designapplication. READ MORE

  6. 5. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

    Author : Lukas Jonasson; [2023]
    Keywords : Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

    Abstract : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. READ MORE
