Watch a seminar presentation exploring the innovative field of beyond-nearest-neighbour metamaterial design, where Dr. Gregory Chaplain from the University of Exeter delves into engineering acoustic and elastic wave dispersion through extended spatial coupling. Learn about experimental studies demonstrating how mixed waveguide-surface wave coupling in acoustics and reconfigurable elastic scaffolds can create unique dispersion relations with extrema within the first Brillouin zone. Discover the effects of structural symmetries on these exotic wave behaviors and understand the background and motivations driving this emerging trend in metamaterial research. The presentation includes collaborative work with Timothy A. Starkey, Daniel B. Moore, Ian R. Hooper, J. R. Sambles, and Alastair P. Hibbins, offering comprehensive insights into this cutting-edge field of engineering physics.
