Title: Structured surfaces as optical metamaterials

Abstract:  If a metamaterial can be defined as a deliberately structured material that possesses physical properties that are not possible in naturally occurring materials, surely deliberately structured surfaces that possess optical properties not found in naturally occurring surfaces can be considered to be optical metamaterials.  Such surfaces can be periodically or randomly structured. Indeed, in the past few years, interest has arisen in optical science in structured surfaces designed to display desirable optical properties that planar surfaces do not possess. After a brief description of such surfaces and their properties, I will describe approaches developed recently by my colleagues and myself to the design of one-and two-dimensional random or deterministic rough surfaces that scatter or transmit light to produce fields that possess specified angular, coherence, spatial, or wavelength properties. In addition I will present a surface structure that produces the negative refraction of a surface plasmon polariton. Finally, I will show how the average over the ensemble of realizations of the surface profile function used in the design of randomly rough surfaces with specified scattering/transmission properties can be replaced in the theory and in experiments by the illumination of a single realization of the random surface by a broadband source.

Title: Collective Plasmons and Their Influence on the Optical Response of Metallic Nanostructures

Abstract:   The presentation will be begin with an elementary discussiom of the origin of the very large enhanced electromagnetic fields often invoked to explain surface enhance Raman scattering (SERS) along with a review of other mechanics which enter.
