Quasi Two-dimensional Transfer of Elastic Waves
, 2001 A theory for multiple scattering of elastic waves is presented in a random medium bounded by two ideal free surfaces, whose horizontal size is infinite and whose transverse size is smaller than the mean free path of the waves.

BuildingsCarbonation depth is essential to determine the durability and predict the remaining service life of concrete structures. This study proposes a multi-frequency Rayleigh wave approximation method (MFRWA) to evaluate carbonation depth by exploiting the ...

Finite element simulations of surface effect on Rayleigh waves
AIP Advances, 2018 Rayleigh waves influenced by surface effect are investigated by using finite element methods, in which eigenfrequency analysis are performed on a model composed of a half-space covered by the surface effect dominated domain.

Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index
Advanced Photonics Research, EarlyView.Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Archives of Acoustics, 2018 Bone loss is one of the serious health issues in bedridden patients or young generation due to lack of physical activities. Mechanical forces are exerted on the bones through ground reaction forces, liquid loadings and by other contraction activities of ...

Resonance Expansions and Rayleigh Waves [PDF]
Mathematical Research Letters, 2001 The author studies expansions of solutions of the wave equation in a compact set with initial data supported in the same set. He considers the general framework of the ``black box scattering'' introduced by Sjöstrand and Zworski. In particular, this includes the classical case of scattering by obstacle with Dirichlet or Neumann boundary conditions and ...

Rayleigh-Wave-Attenuation Measurements [PDF]
The Journal of the Acoustical Society of America, 1962 An experimental method has been developed for measuring attenuation of Rayleigh waves propagating in metal plates. Rayleigh waves are generated at one end of a plate using either a y-cut crystal or an x-cut crystal mounted on a Lucite wedge. The waves propagate along the plate, the lower part of which is immersed in water. Mode conversion occurs at the

Advanced Photonics Research, EarlyView.A graphene‐based bowtie plasmonic nanotweezer is designed and optimized using particle swarm optimization and transfer matrix analysis. The structure achieves strong field confinement, delivering trapping forces up to 6 nN W−1 for 10 nm bioparticles with sixfold lower power requirements than conventional designs.

Advanced Photonics Research, EarlyView.A Ge2Sb2Te5 (GST)‐based microring resonator is designed and simulated on a ZnSe‐platform that operates in the long‐wave infrared (LWIR) wavelength of 8 μm. The structure demonstrates strong power confinement and high Q‐factor. GST resonator is used for gas and biosensing applications.
