# Goos-Hanchen shift at the reflection of light from the complex structures composed of superconducting and dielectric layers

## TL;DR

This paper theoretically investigates the Goos-Hanchen shift in light reflected from layered structures with superconducting and dielectric materials, showing how temperature and film positioning influence lateral shift values.

## Contribution

It introduces a theoretical analysis of the Goos-Hanchen effect in complex superconducting-dielectric layered structures, highlighting the effects of anisotropy and temperature control.

## Key findings

- Lateral shift is strongly affected by the superconducting film's position.
- Temperature variation enables control of lateral shifts near pseudo-Brewster angles.
- Significant lateral shifts occur at grazing incidence for TM-polarized light.

## Abstract

The Goos-Hanchen effect of light reflected from sandwich (three-layered) structures composed of a superconducting YBa2Cu3O7 film and two different dielectric films is investigated theoretically. It has been shown that optical anisotropy of YBa2Cu3O7 film, as well as its positions in the three-layer specimen, strongly effects on the lateral shift values. We have shown that, for all positions of the superconducting film in the three-layered structure, variation of temperature makes possible to control the values of the lateral shift of TE-polarized light at the incidence angles close to pseudo-Brewster angles, whereas for TM-polarized light the lateral shift is only significant at grazing incidence.
