Preface The second volume of the Handai Nanophotonics Book Series features "Nanoplasmonics," a recent hot topic in nanophotonics, impacting a diverse range of research disciplines from information technology and nanotechnology to bio- and medical sciences. The interaction between photons and metal nanostructures leads to interesting and extraordinary scientific phenomena and produces new functions for nano materials and devices. Newly discovered physical phenomena include local mode of surface plasmon polariton excited in nanoparticles, hot spots on nano-rods and nano-cones, long range mode of surface plasmons excited on thin metal films, and dispersion relationship bandgaps of surface plasmons in periodic metal structures. These have been applied to, for example, single molecule detection and nano-imaging/spectroscopy, photon accumulation for lasing applications, optical nano-waveguides and nano-circuits. In July 2004, we had a two-day symposium with distinct scientists to discuss the latest progress in this exciting field. The second volume was co-authored by those participants. The book starts with a statement by John Pendry, the pioneer of nanoplasmonics. The first part, the theory of nanoplasmonics, includes four chapters written by Shalaev, Martin-Morenoa, Fukui, and Takahara. The second part, plasmonic enhanced spectroscopy and molecular dynamics, is written by Watanabe, Futamata, Hayashi, Ishida, Kajikawa, Ozaki, and Asahi. In part 3, recent progress of plasmonic materials and devices are reviewed by Okamoto, Pileni, Yamada, Yoshikawa, Sun, and Ishihara. In addition, we had quite a few participants sharing the common interest in exciting nanophotonics science, although they were not able to contribute to this book. We would like to thank all the contributors and participants to the Handai Nanophotonics Book Series and Handai Nanophotonics Symposium 2. Satoshi Kawata and Hiroshi Masuhara at Handai, Suita, Japan iiv Dedicated to the late professor Osamu Nakamura Osamu Nakamura Professor of Applied Physics and Frontier Biosciences, March 23, 1962 to January 23, 2004, who has ever loved the optical science and microscopy. Osamu Nakamura made a great contribution to computed-tomography microscopy, confocal laser microscopy, super-resolved nano-imaging theory, near-infrared bio-medical spectroscopy, and many other related nano-scale photon science and technologies. He has served the international community by organizing international conferences, inviting international scientists and students to Osaka, and fostering international research collaborations. He published a number of papers in nanophotonics and biophotonics, for imaging analysis, diagnosis, and fabrication. Professor Nakamura visited the conference site of the Handai Nanophotonics Symposium II in July 2004 in his wheel chair and exchanged friendship with his old friends. In his funeral, hundreds of his friends and students came to farewell him. eW all miss him, and wish he will guide us. iiiv Organization of The International Nanophotonics Symposium Handai on Plasmonics: from fundamentals ot applications Sponsored by Nanotechnology Researchers Network Center of Japan The Murata Science Foundation Handai Frontier Research Center, Osaka University Nanonet The Ministry of Education, Culture, Sports, Science and Technology has started Nanotechnology Support Project, the five year project, ot strategically promote Japanese nanotechnology research collaborations among industry, academia, and government.

So closely is light linked to our understanding of the world that "I see" can mean the same as "I understand". Light brought the first information about the distant objects of our universe, and light revealed the first secrets of the microscopic world. Yet in recent times, despite its continuing importance in our lives, there are signs that light is losing its grip on the frontiers of technology. To 'see' the very small we turn to the electron microscope, or the scanning tunneling microscope. These tools are commonly deployed in the world of nanotechnology which is the focus of huge research investment and, through the semiconductor chip, has already revolutionised our lives. The photon with its scarcely sub-micron wavelength is a clumsy and myopic beast in this new world where the electron easily outclasses it in compactness. Electronics has very much led the field in the world of nanotechnology all the way from integrated circuits to quantum dots. Yet the photon's ability to move around so rapidly with minimal disruption of the medium is still prized: there is still work to be done by this ancient tool. Here plasmonics steps into the limelight. A synthesis between light and the collective motion of electrons, the plasmon can move almost as quickly as light, but can also be gathered into incredibly small dimensions to challenge the electron itself in compactness. It naturally inhabits the world of nanotechnology. In this book we have articles by the leaders in this new field. As yet the commercial applications are relatively modest, but the promise is huge and the rich variety of topics represented shows just how much potential is waiting to be unlocked by our researchers.

Shalaev ~ aEthertronics Inc., San Diego, CA 92121, bDepartment of Physics, The University of Texas at Austin, Austin, TX 78712 ~School of Electrical and Computer Engineering, Purdue University, West Lafayette, IN 47907 The optical properties of nanostructured metamaterials have been intensively studied during the last decade. It has been proposed by Pendry, who further developed earlier studies on negative refraction 1,2 that a metamaterial with negative dielectric permittivity c and negative magnetic permeability g could be used for developing a super-lens providing a sub-wavelength resolution. According to Pendry, when the scattered light passes through a material with a negative refractive index (specifically, when n=~fe-~=-I and the two impedances are matched), the evanescent components of the scattered field grow exponentially, allowing the restoration of the scattered image with subwavelength resolution. Smith, Padilla, Vier, and Shultz 3 have demonstrated negative-refraction materials in the microwave range. These materials are also referred to as double-negative or left-handed materials (LHMs), because the electric field and magnetic field along with the wavevector form a left-handed system in this case. In addition to super resolution, the unusual and sometimes counter-intuitive properties of LHMs make them very promising for applications in resonators, waveguides and other microwave and optical elements (see 4 and 5-7). Huge enhancement of the local em field, accompanying the subwavelength resolution, can be used to enhanced Raman and nonlinear spectroscopy of atoms and molecules distributed over the surface of a LHM. In spite of large efforts LHMs have not been demonstrated yet in the optical range. To obtain a negative refraction in the optical range, one needs to have a metamaterial with optical magnetism, which is a challenging problem because magnetism is typically weak in the hi~h-freauencv range.
