Reflection from a multi-species material and its transmitted effective wavenumber
Artur L. Gower, Michael J. A. Smith, William J. Parnell +1
We formally deduce closed-form expressions for the transmitted effective wavenumber of a material comprising multiple types of inclusions or particles (multi-species), dispersed in…
Deepening subwavelength acoustic resonance via metamaterials with universal broadband elliptical microstructure
William D. Rowley, William J. Parnell, I. David Abrahams +3
Slow sound is a frequently exploited phenomenon that metamaterials can induce in order to permit wave energy compression, redirection, imaging, sound absorption and other special f…
Loss Compensation in Time-Dependent Elastic Metamaterials
Daniel Torrent, William J. Parnell, Andrew N. Norris
Materials with properties that are modulated in time are known to display wave phenomena showing energy increasing with time, with the rate mediated by the modulation. Until now th…
Band Gap Formation and Tunability in Stretchable Serpentine Interconnects
Pu Zhang, William J. Parnell
Serpentine interconnects are highly stretchable and frequently used in flexible electronic systems. In this work, we show that the undulating geometry of the serpentine interconnec…
