Are Fresnel filtering and the angular Goos–Hänchen shift the same?

, 2013
The law of reflection and Snell's law are among the tenets of geometrical optics. Corrections to these laws in wave optics are respectively known as the angular Goos–Hänchen shift and Fresnel filtering.

Reverse relative Goos-Hänchen effect

, 2002
A reverse Goos-Hänchen displacement between TE and TM polarizations is predicted and experimentally isolated. The necessary reversal of the evolution of the difference between the phase retardances for the TE and TM reflections vs.

Experimental Observation of Laser Planar Trapping

Optics
This study experimentally demonstrates transverse symmetry breaking—a mechanism governing laser planar trapping—and distinguishes its unique role from related phenomena such as the lateral Goos–Hänchen shift and angular deviations.

Negative Goos-Hanchen shift in periodic media

We show that, under certain conditions, a negative Goos–Hänchen shift—a longitudinal displacement of a totally internally reflected wave packet—occurs in periodic media such as waveguide arrays.Peer ...

Polarization-dependent Goos-Hänchen shift at a graded dielectric interface

, 2010
\u3cp\u3eWe examine the polarization differential Goos-Hänchen beam shift upon total internal reflection, for a graded-index dielectric interface. We find a generic scaling law where the magnitude of this shift depends solely on the product of wavelength

Observation of Goos-Hänchen Shift under Normal Incidence in Slanted TiO2 Nanogratings

npj Nanophotonics
Goos-Hänchen (GH) shifts at natural optical interfaces are typically small. Recent studies have shown that strong optical resonances of metasurfaces and nanogratings can dramatically enhance the GH shifts.

Angular Deviations, Lateral Displacements, and Transversal Symmetry Breaking: An Analytical Tutorial

Photonics
The study of a Gaussian laser beam interacting with an optical prism, both through reflection and transmission, provides a technical tool to examine deviations from the optical path as dictated by geometric optics principles.

Microwave Phase Measurements Associated with the Goos–Hänchen Shift

, 1972
Microwave phase measurements, using the Robertson homodyne detection method, have been made in the field outside a dielectric prism after microwave energy has experienced total internal reflection. The phase changes that occur in this case are explained

Distortion management of the Goos–Hänchen shifts in reflection–transmission beams

, 2018
A new scheme focusing on modification and control of distortion in the reflection and transmission of Goos–Hänchen (GH) shifted beams, is discussed. The absorptivity, reflectivity, and transmissivity are measured for the new atomic scheme.
