Plasmonic phenomena in metals are commonly explored within the framework of classical
electrodynamics and semiclassical models for the interactions of light with free-electron …

Investigating the interaction of electron beams with materials and light has been a field of
research for more than a century. The field was advanced theoretically by the rise of …

The microscopic definition of plasmons in nanosystems is a tremendous challenge. Any
sharp distinction of the excitation nature (nonplasmonic vs plasmonic) becomes blurred at …

Substrate development in surface-enhanced Raman spectroscopy (SERS) continues to
attract research interest. In order to determine performance metrics, researchers in …

The investigation of particle plasmons in metal nanoparticles has predominantly relied on
local optical response approximations. However, as the nanoparticle size approaches the …

This thesis provides a comprehensive introduction to two active research directions within
the field of plasmonics:(i) nonclassical, or quantum, aspects of the plasmonic response; and …

Features of the surface plasmon from macroscopic materials emerge in molecular systems,
but differentiating collective excitations from single-particle excitations in molecular systems …

The capability of collective excitations, such as localized surface plasmon resonances, to
produce a versatile spectrum of optical phenomena is governed by the interactions within …

Interference patterns are not only a defining characteristic of waves, but also have several
applications; characterization of coherent processes and holography. Spatial holography …

Broadband absorbers show great potential in many scientific and technical applications. For
most practical applications, the absorption bandwidth is one of the most substantial metrics …
