Modelling microstructured media: periodic systems and effective media, of solid-state physics: it is essential to understand how structure on a micro-scale affects longer scale macro-scale behaviour and periodic systems are a naturally place to begin. Periodic systems are, on one hand, quite special and the constructive interference created by periodicity leads to str

Pendry’s perfect lens heavily relies upon existence of surface plasmons that exist on its boundaries. Correspondences with acoustics are the

Explicit Models for Surface, Interfacial and Edge Waves,ered structure are incorporated. A hyperbolic-elliptic duality of surface and interfacial waves is emphasized along with a parabolic-elliptic duality of the edge bending wave on a thin elastic plate. The validity of the model for the Rayleigh wave is illustrated by several moving load problems.

Trapped Modes and Edge Resonances in Acoustics and Elasticity,plex resonance frequencies are shown to appear through approximate models and general principles. Eventually, we focus on elastic wave localization near traction free edges in plates and rods. The complicated polarization of the wave in elasticity is shown to increase the ability for trapping with very simple geometries.
