Goos-Haenchen and Imbert-Fedorov shifts of a nondiffracting Bessel beam

TL;DR

This paper investigates how the Goos-Haenchen and Imbert-Fedorov shifts, which are optical phenomena occurring at interfaces, behave when applied to nondiffracting Bessel beams instead of traditional Gaussian beams.

Contribution

It provides the first analysis of these shifts specifically for nondiffracting Bessel beams, expanding understanding beyond Gaussian beam studies.

Findings

Demonstrates that Bessel beams exhibit unique shift behaviors compared to Gaussian beams.

Shows that nondiffracting nature influences the magnitude and direction of optical shifts.

Provides theoretical insights into the reflection and transmission properties of Bessel beams.

Abstract

Goos-Haenchen and Imbert-Fedorov shifts are diffractive corrections to geometrical optics that have been extensively studied for a Gaussian beam that is reflected or transmitted by a dielectric interface. Propagating in free space before and after reflection or transmission, such a Gaussian beam spreads due to diffraction. We address here the question how the Goos-Haenchen and Imbert-Fedorov shifts behave for a ``nondiffracting'' Bessel beam.
