  1. 1. Design and Construction of a Multi-Port Beamsplitter Based on Few-Mode-Fibers

    University essay from Linköpings universitet/Informationskodning

    Author : Daniel Spegel-Lexne; [2022]
    Keywords : beamsplitter; spatial modes; Space division multiplexing; superpositions; LP-modes; few-mode fibers; multi-mode interference; self-imaging; heterogeneous fiber structures; quantum communication; quantum optics;

    Abstract : A MBS (Multi-port beamsplitter) for higher dimensional quantum communication has been designed and constructed and the theory and method for this is presented in this thesis. It uses optical fibers in a heterogeneous structure with a single-mode fiber spliced to a multi-mode fiber and then spliced to a few-mode fiber. READ MORE

  2. 2. Modelling and Simulation of a bridge interacting with a moving vehicle system

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Rui Duan; Jingrui Yang; [2013]
    Keywords : Vehicles-bridge coupling vibration; Dynamic system; D’Alambert principle; Euler–Bernoulli beam theory; Mode superposition method; Newmark-beta method;

    Abstract : The problem about the vibration of vehicles and bridge is mainly the problem of coupling vibration between the vehicles dynamic system and bridge dynamic system. The vehicles running on the bridge at some speed can make the bridge vibrate, at the same time the vibration of the bridge will also affect the vibration of the vehicles. READ MORE

  3. 3. Goal Oriented Estimation of Errors due to Modal Reduction in Dynamics

    University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Author : Sandeep Shetty; Chukwudi Anthony Okeke; [2007]
    Keywords : Dynamic response; Mode superposition; Harmonic loads; Cantilever beam; Number of modes; Displacements; Stresses; Error estimation; Error contribution;

    Abstract : The aim of this thesis is the estimation of errors due to reduction in modal superposition method. Mode superposition methods are used to calculate the dynamic response of linear systems. In modal superposition method, it becomes unnecessary to consider all the modes of a particular system.
