Abstract

This chapter focuses on the plasmonic effects that appear in the ellipsometric functions and the pseudodielectric function when metal thin films and nanoparticles are analyzed by spectroscopic ellipsometry in the visible, near infrared and ultraviolet regions of the electromagnetic spectrum. The chapter is structured in two large sections. The first section reviews the basics of total internal reflection ellipsometry (TIRE), based on the excitation of surface polaritons in metal thin films. The conditions required to excite polaritons in TIRE systems are analyzed along with the main characteristics of those electromagnetic waves. The second section of the chapter is devoted to study the optical properties of plasmonic resonances in nanostructures and the characteristics introduced in the dielectric functions. The treatment of optical anisotropies and Fano resonances in the ellipsometric models is discussed. The last section of the chapter reviews the state of the art of the technique in biosensing applications.
