Collimation aligns a telescope's parts for the sharpest images. Most telescopes need collimation at some point; reflectors need it often. Tools like laser collimators or Chashires help align the ...

In analogy with the electromagnetic case, the main actors necessary for the appearance of both enhanced transmission and collimation in acoustics are the acoustic surface waves (ASWs). There are many ...

New observations from the National Science Foundation National Radio Astronomy Observatory's (NSF NRAO) Karl G. Jansky Very Large Array (NSF VLA) provide compelling evidence supporting a universal ...

A series of studies of "ideal" beams has been carried out using Monte Carlo simulation with the goal of providing guidance for the design of epithermal beams for boron neutron capture therapy (BNCT).
