Two interacting supersonic water jets and collisions of a jet with an aluminum target are studied experimentally by hydrodynamic simulations. Supersonic form, when shocks generated underwater electrical explosions conical wire arrays converge. The supplied ∼250 kA, ∼1 μs rise time current pulse. Underwater explosion two placed face to produces propagating in air velocities ∼2.5×103 m/s leading ...

Sub-diffraction-limit resolution, or superresolution, has been successfully demonstrated in recent theoretical and experimental studies for two equal-brightness incoherent point sources. However, practical situations of either nonequal brightness (i.e., unbalancedness) partial coherence are shown to have fatal effects on such superresolution. As a step towards resolving issues, we consider the ...
