Seismic studies on the Derbyshire dome [PDF]
, 1983 The Derbyshire Dome is thought to have been a stable uplifted area since at least Lower Carboniferous times. This project is principally concerned with four 30km seismic refraction lines which crossed the limestone outcrop of Derbyshire and N ...

Uniform refraction in negative refractive index materials [PDF]
Journal of the Optical Society of America A, 2015 We study the problem of constructing an optical surface separating two homogeneous, isotropic media, one of which has a negative refractive index. In doing so, we develop a vector form of Snell's law, which is used to study surfaces possessing a certain uniform refraction property, both in the near and far field cases. In the near field problem, unlike

Ray-optical refraction with confocal lenslet arrays [PDF]
, 2008 Two parallel lenslet arrays with focal lengths f1 and f2 that share a common focal plane (that is, which are separated by a distance f1+f2) can refract transmitted light rays according to Snell's law, but with the 'sin's replaced with 'tan's. This is the

Critique of optical negative refraction superlensing [PDF]
, 2011 Has the ten-year old quest for the optical superlens, based on Veselago’s hypothesis of negative refraction, been a chimera? We argue that Pendry’s alternative prescription of the silver superlens is nothing more than an application of the natural ...

Refraction of nonlinear light beams in nematic liquid crystals [PDF]
, 2013 Optical spatial solitons in nematic liquid crystals, termed nematicons, have become an excellent test bed for nonlinear optics, ranging from fundamental effects to potential uses, such as designing and demonstrating all-optical switching and routing ...

Refraction problems after refractive surgery
Survey of Ophthalmology, 1988 While refractive surgery such as radial keratotomy, epikeratophakia, and corneal relaxing incisions offer many potential benefits to patients, they can also generate optical problems such as overcorrection or undercorrection of the prior refractive error and variable vision.

Wave scattering by small bodies and creating materials with a desired refraction coefficient [PDF]
, 2011 In this paper the author’s invited plenary talk at the 7-th PACOM (Pan African Congress of Mathematicians), is presented. Asymptotic solution to many-body wave scattering problem is given in the case of many small scatterers. The small scatterers can be

Refraction in radioastronomy [PDF]
Symposium - International Astronomical Union, 1979 In the last few years there was no paper in the astronomical literature reporting on new measurements of radioastronomical refraction. But there are some important review papers on different aspects of this topic, e.g. on the ionosphere by M.M. Komesaroff (1960) and T.
