The present thesis deals with the exploration of phononic
properties of meso- and nanostructured colloid-based composite
materials at hypersonic (GHz) frequencies. The emerging field of
phononics, the mechanical analogue of photonics, treats the
propagation and manipulation of acoustic waves in structured
materials. Due to their widely tunable properties (size, density,
etc.) and their ability to self-assembly, polymer colloids are
ideal systems to realize hypersonic phononics, which are
investigated by Brillouin light scattering herein. Therefore, both
the mechanical and physical properties of the individual colloidal
particles, which manifest in their resonance vibrations
(eigenmodes), as well as the acoustic propagation in colloidal
structures have been investigated. This thesis already lead to
several journal publications and seven presentations at
international conferences, and was honored summa cum laude.
