Query: Airy beams and accelerating waves: An overview of recent advances   Over the last dozen of years, the area of accelerating waves has made
considerable advances not only in terms of fundamentals and experimental
demonstrations but also in connection to a wide range of applications. Starting
from the prototypical Airy beam that was proposed and observed in 2007, new
families of accelerating waves have been identified in the paraxial and
nonparaxial domains in space and/or time, with different methods developed to
control at will their trajectory, amplitude, and beam width. Accelerating
optical waves exhibit a number of highly desirable attributes. They move along
a curved or accelerating trajectory while being resilient to perturbations
(self-healing), and, are diffraction-free. It is because of these particular
features that accelerating waves have been utilized in a variety of
applications in the areas of filamentation, beam focusing, particle
manipulation, biomedical imaging, plasmons, and material processing among
others.
