This talk will provide an overview of techniques being used in elastic wave systems to control, redirect or manipulate waves. Systems of graded sub-wavelength resonators allow for mode conversion between wave types and wave systems, graded index lenses create opportunities to focus or redirect waves and phononic crystals can be used to create zero-frequency bandgaps. Each of these mechanisms will be illustrated.
The seminar will take place on the occasion of the Colloquia Doctoralia – XXX Cycle, PhD programme in Structural, Seismic and Geotechnical Engineering.
