  1. 1. On multilayered system dynamics and waves in anisotropic poroelastic media

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Juan Pablo Parra Martinez; KTH.; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poroelastic media; anisotropy; plane waves; multilayered systems; dynamics; acoustics; optimisation; matériaux poro-visco-élastique; anisotropie; ondes planes; panneaux multicouches; dynamique; acoustique; optimisation; Poroelastiska material; anisotropi; planvågor; flerskiktssystem; dynamik; akustik; optimering; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : The mechanical and acoustic anisotropy of media is a governing factor in the behaviour of multilayered systems including such media. The understanding of the mechanisms conditioning the dynamic behaviour of multilayered systems is of paramount importance. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transformation optics; Maxwell’s equations; invisibility cloaks; compensated bilayer; perfect imaging; optical illusion; nihility media; α media; NATURAL SCIENCES Physics Other physics Optics; NATURVETENSKAP Fysik Övrig fysik Optik;

    Abstract : Transformation optics, a recently booming area, provides people a new approach to design optical devices for manipulating light. With transformation optics, a lot of novel optical devices are proposed, such as invisibility cloaks, optical wormholes, optical black holes, illusion devices. READ MORE

  4. 4. Non-Invasive Multidimensional Imaging Applied on Biological Substances

    University dissertation from Göteborg : Chalmers university of technology

    Author : Anders Kaestner; Högskolan i Halmstad.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microwave propagation; Tomography; Polarimetry; Frequency estimation; Anisotropic media; Wood; Muscles; Paper; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis presents the research and development of a microwave in-strument to capture tomographic information from the inner structure ofthe biological sample. The principle of the instrument is based on theanisotropy introduced by the fibres in materials such as wood and musclesin terms of information regarding changes in the fibre structure. READ MORE

  5. 5. High-speed stereo imaging for the characterization of anisotropic viscoelastic media

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Luca Manzari; Peter Göransson; Jacques Cuenca; Ines Lopez Arteaga; Mathieu Aucejo; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Abstract : This thesis proposes an experimental method for observing and characterizing the viscoelastic properties of anisotropic media using high-speed white light stereo imaging. The method uses short-time video recordings of a specimen undergoing forced harmonic motion. READ MORE
