Course Instructor
SC1140: Surface Multiplasmonics
This course will present the methodology of formulating and solving for surface plasmon polariton (SPP) waves guided by the interface of a metal with a periodically nonhomogeneous dielectric material film such as a photonic crystal or a sculptured thin film. Such interfaces can support more than one SPP wave at the same frequency but with different phase speeds, attenuation rates, and degrees of localization to the interface. The main goal of the course is to make the participants aware of the basic machinery of electromagnetics used for research on surface waves. The knowledge gained during the course will also be applicable to other types of surface waves such as Tamm waves.
SC664: Thin Films with Engineered Nanomorphology
This course provides attendees with a basic knowledge of the morphology and the optical response characteristics of Sculptured Thin Films (STFs), which are nanoengineered by directional physical vapor deposition (PVD) onto surfaces at oblique angles. The first part of the course focuses on the nanowire-shaped morphology of STFs at the 1-1000 nm length scales, with emphasis on growth techniques and ways to achieve distinct engineered nanomorphologies through simple movements of the substrate during growth. The second part of the course focuses on the modeling of STFs, the effect of morphology on reflection and transmission characteristics, and the principles underlying STF devices such as filters, polarizers, sensors and radiators. Computer programs are provided as part of the course.
