Anomalous refraction of optical spacetime wave packets [PDF]
Nature Photonics, 2019 Refraction at the interface between two materials is fundamental to the interaction of light with photonic devices and to the propagation of light through the atmosphere at large1. Underpinning the traditional rules for the refraction of an optical field

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 ...

Depth perception on fundus images using a single-channel stereomicroscopy
Journal of Innovative Optical Health Sciences, 2021 Typical fundus photography produces a two-dimensional image. This makes it difficult to observe the microvascular and neural abnormalities, because the depth of the image is missing. To provide depth appreciation, we develop a single-channel stereoscopic
