Nanophotonics & Plasmonics

1860s Maxwell’s equations have come a long way to give birth the fascinating fields of Nanophotonics and Plasmonics, where the electromagnetic waves are manipulated and investigated in materials structured at the wavelength scale. This course is designed to provide an introduction to the fundamentals and applications of nanophotonics and its sub-field of plasmonics. It will guide the student from Maxwell’s equations of electrodynamics to the frontier of the current, state-of-the-art research. The student will discover its broad and strong impact in near-field microscopy, optical nanoantennas, optical interactions, photonic crystals, photonic/plasmonic waveguides, optical and electron spectroscopies, metamaterials, and non-linear optics.
