Dark solitons at nonlinear interfaces [PDF]
, 2010 The refraction of dark solitons at a planar boundary separating two defocusing Kerr media is simulated and analyzed, for the first time (to our knowledge). Analysis is based on the nonlinear Helmholtz equation and is thus valid for any angle of incidence.

Land-Streamer vs. Conventional Seismic Data for High-Resolution Near-Surface Surveys
Applied Sciences, 2022 Near-surface high-resolution seismic mapping is very important in many applications such as engineering and environmental. However, the conventional setup of the seismic technique requires planting geophones, connecting cables, and then collecting all ...

Perfect control of reflection and refraction using spatially dispersive metasurfaces [PDF]
, 2016 Nonuniform metasurfaces (electrically thin composite layers) can be used for shaping refracted and reflected electromagnetic waves. However, known design approaches based on the generalized refraction and reflection laws do not allow realization of ...

Anomalous Refraction of Acoustic Guided Waves in Solids with Geometrically Tapered Metasurfaces. [PDF]
Physical Review Letters, 2016 The concept of a metasurface opens new exciting directions to engineer the refraction properties in both optical and acoustic media. Metasurfaces are typically designed by assembling arrays of subwavelength anisotropic scatterers able to mold incoming ...

Negative Refraction and Left-handed electromagnetism in Microwave Photonic Crystals [PDF]
, 2004 We demonstrate negative refraction of microwaves in metallic photonic crystals. The spectral response of the photonic crystal, which manifests both positive and negative refraction, is in complete agreement with band-structure calculations and numerical ...

Negative index of refraction in optical metamaterials. [PDF]
Optics Letters, 2005 A double-periodic array of pairs of parallel gold nanorods is shown to have a negative refractive index in the optical range. Such behavior results from the plasmon resonance in the pairs of nanorods for both the electric and the magnetic components of ...

Amphoteric refraction at the interface between isotropic and anisotropic media [PDF]
, 2006 It is found that the amphoteric refraction, i.e. the refraction can be either positive or negative depending on the incident angles, could occur at a planar interface associated with a uniaxially anisotropic positive index media (PIM) or an anisotropic ...
