Propagation-invariant space-time caustics of light [PDF]
Caustics are responsible for a wide range of natural phenomena, from rainbows and mirages to sparkling seas. Here, we present caustics in space-time wavepackets, a class of pulsed beams featuring strong coupling between spatial and temporal frequencies ...

Dynamic crack propagation characteristics of media with bedding under an impact load
With the gradual development of mines, tunnels, and other underground constructions, theoretical research on the influence of internal defects in rock structure on rock dynamic fracture behavior and related engineering practices are of great importance ...

Negative refraction usually demands complex structure engineering while it is very natural for massless Dirac fermions (MDFs) across the p–n junction (PNJ), this leads to Dirac electron optics.

Caustic ingestion in children: A 6-year retrospective study
Some aspects of the management of caustic ingestion in children are still debated. We aimed to determine the predictive value of epidemiological and clinical features of caustic ingestion, and to define guidelines adherence. This is a retrospective study

Caustics of developable surfaces [PDF]
Abstract While considering a mirror and light rays coming either from a point source or from infinity, the reflected light rays may have an envelope, called a caustic curve. In this paper, we study developable surfaces as mirrors. These caustic surfaces, described in a closed form, are also developable surfaces of the same type as the

Based on the principles of geometrical optics, an analytical description of caustics generated in a spherical mirror is presented. The formation of caustics in a wave field is studied using acoustic and electromagnetic waves as an example.

A maskless method of electron beam lithography is described which uses the reflection of an electron beam from an electrostatic mirror to produce caustics in the demagnified image projected onto a resist–coated wafer. By varying the electron optics, e.g.

Spectral Caustics in Attosecond Science
A unique type of singularity common in wave phenomena, known as caustics, links processes observed in many different branches of physics [1]. We investigate the role of caustics in attosecond science and in particular the physical process behind high ...
