Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

Simple explicit localized solutions are systematized over the whole space of a linear wave
equation, which models the propagation of optical radiation in a linear approximation. Much …

The first article by Turunen and Friberg deals with a class of fields with propagation-invariant
properties such as the optical intensity distribution. Coherent and partially coherent …

In this paper it is shown how one can use Bessel beams to obtain a stationary localized
wave field with high transverse localization, and whose longitudinal intensity pattern can …

The Lorentz transformations of propagation-invariant localized waves (also known as
nondispersive or nondiffracting or undistorted progressive waves) are studied in the …

The group velocity of 'space-time'wave packets–propagation-invariant pulsed beams
endowed with tight spatio-temporal spectral correlations–can take on arbitrary values in free …

In this work, starting by suitable superpositions of equal-frequency Bessel beams, we
develop a theoretical and experimental methodology to obtain localized stationary wave …

Introducing precise spatiotemporal structure into a pulsed optical field can lead to
remarkable changes with its free propagation.“Space-time”(ST) wave packets, for example …

We investigate the properties of the recently introduced time-diffracting (TD) beams in free
space. They are shown to be paraxial and quasimonochromatic realizations of …

The vector form of X-Waves is obtained as a superposition of transverse electric and
transverse magnetic polarized field components. It is shown that the signs of all components …
