Effects of diffraction and radiation on a submerged sphere
This paper deals with an investigation of the effects of diffraction and radiation on a submerged sphere in water of finite depth d. We assume that the fluid is homogeneous, inviscid, and incompressible, and the fluid motion is irrotational.

On Sommerfeld radiation conditions for the diffraction problem with two unbounded media
SynopsisA radiation condition is obtained, and is then used together with weighted Sobolev spaces and the limiting absorption method to establish the unique existence of solutions to the diffraction problem for the wave propagation in the case where the propagation speed is piecewise constant, and the surface separating two media is unbounded.

Zeptosecond electron pulse train via multiphoton inelastic Cherenkov diffraction [PDF]
High-harmonic generation and ultrafast electron coherent control are central goals in modern strong-field physics. However, the problem of producing and manipulating electron-matter-wave pulses at zeptosecond timescales remains a major challenge. Here we
