Tailored elastic surface to body wave Umklapp conversion
Gregory J. Chaplain, Jacopo M. De Ponti, Andrea Colombi +7
Elastic waves guided along surfaces dominate applications in geophysics, ultrasonic inspection, mechanical vibration, and surface acoustic wave devices; precise manipulation of sur…
Experimental observations of topologically guided water waves within non-hexagonal structures
Mehul P. Makwana, Nicolas Laforge, Richard V. Craster +4
We investigate symmetry-protected topological water waves within a strategically engineered square lattice system. Thus far, symmetry-protected topological modes in hexagonal syste…
Broadband control of water wave energy amplification in chirped arrays
Aidan J. Archer, Hugh A. Wolgamot, Jana Orszaghova +3
Water waves in natural environments are typically broadband, nonlinear and dynamic phenomena. Taking concepts developed for slow light in optics, we address the challenge of design…
Observations of symmetry induced topological mode steering in a reconfigurable elastic plate
Kun Tang, Mehul P. Makwana, Richard V. Craster +1
We experimentally investigate the valley-Hall effect for interfacial edge states, highlighting the importance of the modal patterns, between geometrically distinct regions within a…
Exciting Pseudospin Dependent Edge States in Plasmonic Metasurfaces
Matthew Proctor, Richard V. Craster, Stefan A. Maier +2
We study a plasmonic metasurface that supports pseudospin dependent edge states confined at a subwavelength scale, considering full electrodynamic interactions including retardatio…
Manipulating Topological Valley Modes in Plasmonic Metasurfaces
Matthew Proctor, Paloma A. Huidobro, Stefan A. Maier +2
The coupled light-matter modes supported by plasmonic metasurfaces can be combined with topological principles to yield subwavelength topological valley states of light. We give a…
