“…In the context of inhomogeneously polarized vector beams, the index m in Equations ( 7) and ( 8) can be assigned to the so-called polarization order p, see Reference [67].…”

“…We have also investigated cases of higher polarization order, with a topological charge of m = 1 (translating to polarization order p = 2 [67]), see Figures 10 and m = 2 (translating to the polarization order p = 3 [67]), see Figure 11. We can see that in the case of Figure 10, there is a minimum intensity in the center of the beam, except for the z component, which has a considerable intensity in the center of the beam.…”

“…We note that this specific condition requires rather large spatial angles of the individual components (up to π/2) and additionally restricts the temporal frequencies ω for which backward propagation of the pulse is possible. Thus, the description of the optical bullets using Equations ( 7) and ( 8) allows us to investigate optical bullets with high polarization orders p [67] or polarization singularities.…”

Theoretical studies on the generation of nondiffracting and nondispersive light pulses and their experimental implementation are one of the renowned problems within electromagnetics. Current technologies enable the creation of short-duration pulses of a few cycles with high power and fluency. An application of these techniques to the field of nondiffracting and nondispersive pulses requires a proper mathematical description of highly focused vector pulses. In this work, we study vector optical bullets in a dielectric medium with different polarization structures: linear, azimuthal, and radial. We report the differences caused by the vector model compared to the scalar model. We analyze effects caused by superluminal, subluminal, or even negative group velocity on the properties of vector optical bullets inside a dielectric material.
