This paper presents the preliminary results of an extensive parametric study on seismic response of two-dimensional semi-sine shaped hills to vertically propagating incident P- and SV-waves. Clear perspectives of the induced diffraction and amplification patterns are given by investigation of time-domain and frequency-domain responses. It is shown that site geometry, wave characteristics , and ...

The ability to confine light subwavelength scales has led exciting developments in fields ranging from sensing single molecule chemistry. In this paper, we demonstrate how arrays of annular hole resonators can be used surface acoustic waves (SAWs) regions the propagating that are much smaller than wavelength SAWs. These microscopic elastic devices for signal processing and and, increasingly, ar...

Surface electromyogram (EMG) detected by electrode arrays along the muscle fibre direction can be approximated by the sum of propagating and non propagating components. A technique to separate propagating and non propagating components in surface EMG signals is developed. The first step is an adaptive filter, which allows obtaining an estimation of the delay between signals detected at differen...

Rayleigh-Bénard and Bénard-Marangoni instabilities have been studied for roughly a century and have served as prototypes for the transition to temporal chaos as well as spatiotemporal chaos of an initially stationary pattern. Using the Marangoni effect [1,2] with an horizontal temperature gradient to drive the system out of equilibrium, one can observe propagating waves instabilities: hydrother...

Finite-thickness slabs of hyperbolic media with tilted optical axes exhibit asymmetry properties for waves propagating upward and downward with respect to slab interfaces. Under certain conditions, asymmetric hyperbolic media acquire extreme permittivity parameters and the difference between upward and downward propagating waves becomes very large. Furthermore, both waves can be perfectly match...
