Figure 1 Refraction of light through a prism Figure 2 shows how the angle of deviation δ changes as the angle θ of the incident ray changes. The specific curve shown is for the prism described in Figure 1. Note that δ goes through a minimum value, about 23° for this specific prism....
By measuring the scattering angle of the transmitted beam through a prism fabricated from this material, we determine the effective n , appropriate to Snell(cid:213)s law. These experiments directly con(cid:222)rm the predictions of Maxwell(cid:213)s equations that n is given by the negative...
These patchy diptychs rather seminarishly conjure Wassily Kandinsky and Gabriele Munter's Hinterglastnalerei, Blue Rider works painted behind glass in the manner of Bavarian peasant exvotos, folkloric saints enlivened by the double refraction of the paint itself when seen through a glass surface. ...
We present an experimental study of optical time-refraction caused by time-interfaces as short as a single optical cycle. Specifically, we study the propagation of a probe pulse through a sample undergoing a large refractive index change induced by an intense modulator pulse. In these systems, in...
Among them, one allows the negative refraction of longitudinal waves transmitted through the PC. The left-handed behaviour of the PC is exhibited numerically as well as experimentally, by using a prism shaped PC. Finally, a numerical simulation is presented, with the PC immersed in a fluid, ...
f The S/P ratio as a function of the frequency, extracted by the output energy of three equally spaced dots A, B and C on the termination normal in d–e. g The corresponding k-space analysis on the out-coupling of the edge states through the zigzag termination. The Brillouin zone (...
