TLDR
Theoretical and experimental study of optical implementations of various new nonspreading wave-packet solutions to linear wave equations is overviewed in this paper, where startling superluminal group velocity of pulsed Bessel beams and so-called X-type waves is discussed and mathematically described in terms of electromagnetic field of a tachyonic source.Abstract:

Evidence of X -Shaped Propagation-Invariant Localized Light Waves
Peeter Saari,Kaido Reivelt +1 more
TL;DR: In this paper, the peculiar spatiotemporal profile of an optical realization of the nonspreading axisymmetric $X$ wave has been recorded, and a simple representation of the wave and its correlation with plane waves has been introduced, which covers also a broader class of incoherent wave fields.

Aperture realizations of exact solutions to homogeneous-wave equations
TL;DR: In this paper, the forward-propagating (causal) components of any homogeneous solution of the scalar-wave equation are actually recovered from either an infinite- or a finite-sized aperture in an open region.

Demonstration of the Bessel-X pulse propagating with strong lateral and longitudinal localization in a dispersive medium.
TL;DR: Experiments on ultrashort pulses that maintain their strong lateral and longitudinal localization in a bulk linear highly dispersive medium and can be applied in femtosecond laser optics are reported.

On localized “X-shaped” Superluminal solutions to Maxwell equations
TL;DR: In this paper, the authors extend for the case of Maxwell equations the "X-shaped" solutions previously found for scalar (e.g., acoustic) wave equations, in that they maintain their shape as they propagate.

Gouy shift and temporal reshaping of focused single-cycle electromagnetic pulses
TL;DR: The role of the Gouy shift in the temporal reshaping and polarity reversals of single-cycle terahertz pulses is elucidated.
