We discuss the wave optical effects in gravitational lens systems with two point mass lenses different planes. identify and vary parameters (i.e., masses, related distances, their alignments) to system investigate on amplification factor. find that due a large number of parameters, it is not possible make generalized statements regarding conclude by noting best approach study two-plane multi-pl...

Projecting on a suitable subset of coordinates, a picture is constructed in which the conformal boundary of AdS 5 × S 5 and those of the plane wave resulting in the Penrose limit is located at the same line. All AdS 5 × S 5 and plane wave geodesics are classified in their integrated form. Performing the Penrose limit the approach of null geodesics reaching the conformal boundary of AdS 5 × S 5 ...

We show that all IIB backgrounds with strictly 28 supersymmetries are locally isometric to the plane wave solution of arXiv:hep-th/0206195. Moreover, we demonstrate that all solutions with more than 26 supersymmetries and only 5-form flux are maximally supersymmetric. The N=28 plane wave solution is a superposition of the maximally supersymmetric IIB plane wave with a heterotic string solution....

In this paper, the scattering of a plane monochromatic electromagnetic wave from a nanowire with circular cross-section in the transverse electric (TE) mode is simulated using the well-known Stratton-Chu surface integral equations. For an ordinary dielectric nanowire the refraction phenomenon is nicely simulated. In the case of a plasmonic nanowire no sign of surface plasmon excitation and prop...
