Title: Electromagnetic standing waves in nano-objects
By Dr. NAGAO, Tadaaki

Abstract: In the past decade, surface-localized
electromagnetic waves as well as those of the low-dimensional variants
have become increasingly important in nanotechnology since their optical
properties are strongly dependent on the size and the shape of the
small objects. Such feature can be utilized for tailoring optical
properties for future nano-photonics/optics devices as well as
high-sensitivity sensors and efficient catalytic materials.
In this
contribution, we plan to introduce our recent results on the optical
absorption spectroscopy by the excitations of standing-wave plasmons (1)
in an array of Metallic atomic chains, atomically thin discs (2)
Lithographically prepared nanoantennas (3) Wet-chemically prepared
islands on silicon substrates. By tuning the preparation conditions, we
tuned the size of these objects and the resonance frequency of the
optical absorption was also systematically shifted as a function of
their geometrical parameters. In some systems the observed behavior was
found to be explained by the plasmonic resonators expected from surface
plasmon polariton (SPP) scenario while in others the behavior was found
to be different from the conventional SPP scenario. We also present our
recent studies on the light-material interactions in efficient energy
conversion and medical diagnostics.

Vietnam is well-known for its rich culture, its delicious food and being an emerging developing country. Less than a century after moving the Kingdom to Thang Long (former name of Hanoi), in 1076, the third King of the Ly dynasty founded in this city the first Vietnamese University, named Quoc Tu Giam (situated in Van Mieu). Hanoi is now a city of preserved culture. It is also the largest center for science and technology of the country. In this year 2010, Hanoi is proud to hold the National Celebration of 1000 years of Thang Long-Hanoi Capital.
