Abstract

The Goos-Hänchen (GH) effect, a well-established optical phenomenon, manifests as a lateral displacement of a reflected or transmitted light beam at the interface between two media. Recent advancements have focused on understanding how complex conductivity, varying spatially within a material, influences these shifts. This study explores the nuanced behavior of position-specific GH shifts under the influence of complex conductive characteristics. By examining the spatial variability of conductivity and its impact on GH shifts, we demonstrate how localized changes in conductivity alter the phase relationships of reflected waves, thereby modulating the magnitude and direction of GH displacements. Experimental observations corroborate theoretical predictions, highlighting the potential for precise control and manipulation of GH shifts through engineered conductivity profiles. This research not only enhances our fundamental understanding of light-matter interactions but also holds promise for applications in optical sensing, materials science, quantum optics, and advanced photonics technologies.
