Thesis title: Exploring the Temperature-dependent Goos-Hänchen shift and its applications in various media
Abstract: The thesis explores the temperature-dependent Goos-Hänchen shift (TGH-shift), a unique electromagnetic phenomenon, particularly its interaction with absorbing media. A deep investigation has
been presented in terms of its theoretical aspects and potential applications in optoelectronics. Despite progress, there is room for further practical exploration, especially in temperature-sensitive
devices. The thesis provides historical context, introduces electromagnetism, and outlines the
methodology used. The study employs the Lorentz-Drude model to examine how the Goos-Hänchen
shift (GH-shift) varies with temperature, focusing on the constitutive parameter’s (permittivity and
permeability) dependency on temperature. Frequency analysis has been mentioned while considering both transverse electric and transverse magnetic polarization scenarios and their variations with
temperature. The main focus is on temperature-independent and temperature-dependent Goos-Hänchen shifts, with case studies providing a deeper understanding and comparisons with prior
research. The study also explores the behavior of reflectivity and phase for different polarization
scenarios. Comparison has been made in terms of the dependency of GH-shifts upon temperature and a discussion of the potential development of temperature-sensitive devices has been
presented.
