Gouy shift and temporal reshaping of focused single-cycle electromagnetic pulses
Abstract
We discuss exact solutions of Maxwell's equations that describe the evolution of single-cycle electromagnetic pulses. The solutions are applied to recent observations of the diffraction transformation of terahertz pulses. In particular, we elucidate the role of the Gouy shift in the temporal reshaping and polarity reversals of single-cycle terahertz pulses.

Spatially limited ultrashort THz pulses change their phase dramatically if they are strongly focused, a phase shift called the Gouy shift.
“However, it has been shown [8,9] that spatially limited ultrashort THz pulses change their phase dramatically if they are strongly focused; this phase shift is called the Gouy shift.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
