Message to anyone who orders in Ariba:

Effective immediately please use the following naming convention for the Title when ordering in Ariba.

BRK/PI(Professor last name)/REQUESTER NAME/ACCT/VENDOR

This will enable us to have the necessary information for approval without actually going through several screens to find the information we need.  This will expedite the approval, receipt, and reconciliation process.

Thank you very much for your help on this!!

Engineering Video Contest
To Purdue Engineers -

Let's show the world what Purdue engineers can do!

In celebration of its upcoming 50th anniversary, the NAE is launching Engineering for You (E4U), a video contest to highlight the impact that engineering has or will have on society. In the last 50 years, engineering achievements include helping to land astronauts on the moon, creating the Internet, and decoding the human genome. What will engineering create in the next 50 years? Rev up your creativity, pull out your camera or phone, and produce a one to two minute video showing the world how you see engineering enhancing quality of life and serving the needs of society. The video must highlight a period during the years 1964-2064. The main prize is $25,000, and the contest will run from Nov. 1, 2013, to March 31, 2014. www.e4uvideocontest.org<http://www.e4uvideocontest.org/>

Physical Facilities Notice

Physical Facilities recently began a new desk-side recycling and trash collection process.
Now, all office waste can be disposed of in the blue desk-side receptacles by putting anything recyclable (paper, cans, bottles) in one section, and non-recyclables (food waste, snack wrappers, facial tissues, napkins and restroom hand towels) in the other.

Design and implementation of Plasmonic Nanocavity Arrays and Their Applications

We investigate and design metal nanostructures with a novel functionality that can be observed under plasmonic resonance. First, we demonstrate high resonant absorption of visible light with a plasmonic nanocavity array fabricated through resistless nanoimprinting in metal (RNIM) method. The nanocavities are shown to be efficiently excited using normally incident light, and the resonant wavelength can be controlled by cavity dimensions. Numerical simulations confirm the experimental observations and illustrate the insensitivity to incident angle. The resonant absorption is due to the excitation of a localized metal-insulator-metal cavity mode. The interacting surface waves allow cavity lengths on the order of ten nanometers for light having a free space wavelength of about four hundred nanometers. Second, we present the design concept of an angle-insensitive optical filter, which is composed of a metal-dielectric multilayer stack. The non-trivial phase shift at the metal-dielectric interface allows a Fabry-Pérot resonance at subwavelength scale and introduces angular insensitivity. The central passband wavelength can be tuned from UV to visible or longer wavelength,
by engineering the dielectric thickness and selecting metallic components with appropriate plasma frequency. Finally, we propose two other potential plasmonic devices for the applications of a silicon waveguide polarization beam splitter and nanotweezers. Initial progress of these works are presented.
