TL;DR: In this article, an attenuated total reflection optical probe consisting of an optical material having a light transmission property in the far ultraviolet region, and having a refractive index that changes continuously, at least in one part thereof, is proposed.
Abstract: PROBLEM TO BE SOLVED: To provide an attenuated total reflection optical probe capable of highly sensitively detecting a micro soluble component in aqueous solution and performing a quantitative determination by easily performing a spectrometry of water in a far-ultraviolet region of less than 180 nm.SOLUTION: This attenuated total reflection optical probe comprises an optical material having a light transmission property in the far ultraviolet region, and has a refractive index that changes continuously, at least in one part thereof. The optical probe includes, on a side in contact with a sample substance, a plane totally reflecting light having incident angle equal to or larger than the critical angle. The refractive index in the far ultraviolet region at a part near the plane including the part of the plane is higher than the refractive indices of the other part and of the sample substance.

18 Oct 2012TL;DR: In this paper, a negative refraction interface composed of a positive and negative refractive index material is realized by using two-dimensional transmission line grids, where the transient interface reflection and refraction properties are studied by time-domain method where the time evolution of an electromagnetic wave as it hits the interface is simulated and measured.
Abstract: A negative refraction interface composed of a positive and negative refractive index material is realized by using two-dimensional transmission line grids. The transient interface reflection and refraction properties are studied by time-domain method where the time evolution of an electromagnetic wave as it hits the interface is simulated and measured. It is found that the wave is trapped temporarily at the interface, reorganizes, and after a certain time, the refractive wave front moves eventually in the negative direction. What's more the refractive wave need longer time to build up than the reflected wave. Experiment results agree well with the simulations.

TL;DR: In this paper, the phase of the refraction coefficient is a multi-valued function of the angle of incidence and power of the incident wave, and it is shown that the phase is a multiview function.
Abstract: We consider total internal reflection of a monochromatic plane wave from an isotropic nonlinear medium with
cubic nonlinearity. Hodograph of the electric field is found from the expression for energy density of the field.
Possible values of angle of incidence are found. Essential differences between waves in focusing and defocusing
media are pointed out and discussed. It is shown that the phase of the refraction coefficient is a multi-valued
function of the angle of incidence and power of the incident wave.

TL;DR: In this paper, the authors considered the reflection from a random medium of light with short coherence length and found that the second order correlation function of light can have a peak in a direction where the reflection angle is equal to angle of incidence.
Abstract: We consider the reflection from a random medium of light with short coherence length. We found that the second order correlation function of light can have a peak in a direction where the reflection angle is equal to angle of incidence. This occurs when the size of the region, from which light is collected, is larger than the coherence length.
