  4. 4. Design of soundproof panels via metamaterial concept

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

    Author : Zibo Liu; KTH.; [2019]

    Abstract : The goal of the work is to find a way to improve the sound insulation properties of different types of panels in order to meet different requirements. Inspired by the nontrivial behavior of the locally resonant acoustic metamaterials, this concept is introduced into the design of structures in order to explore the potential ways to improve the sound insulation behavior in the relevant specific frequency regions.

  5. 5. Exploring metamaterial horizons: New concepts and geometrical tools for the description of advanced electromagnetic phenomena

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Sophie Viaene; [2018]

    Abstract : Einstein’s theory of general relativity has dramatically changed our world view, by describing gravity as an intrinsic deformation of space and time. About fifteen years ago, John Pendry and Ulf Leonhardt had the intriguing idea to emulate the behaviour of light in a deformed space by making use of carefully designed artificial metamaterials.
