2: Nanometric Optical Waveguide based on Surface Plasmon Polaritons
By Prof. Kazuo Tanaka
Department of Electronics and Computer Engineering, Gifu University, JAPAN
Nanometric optical integrated circuits are a key optical technology in future applications such as nano-photonics and near-field optical (NFO) devices. The surface plasmon polaritons (SPPs) on metal surfaces is expected to be employed as a type of nanometric optical wire in such nanoscale integrated optical circuits. We have recently proposed an SPP gap waveguide (SPGW) as a basic element for nanometric optical circuits. The waveguiding mechanism of the SPGW is based on the low phase velocity exhibited by SPPs in nanometrically narrow gap regions between two parallel metal substrates compared to that in wide gap regions. In this talk, I will present computer simulations of SPGWs by using volume integral equations (VIE). Basic characteristics of SPGWs obtained by the simulations and its applications to nano-photonic devices will be explained.

Design and Control of Anthropomorphic Robot
By Prof. Haruhisa Kawasaki
Department of Humand and Information Systems, Gifu University, JAPAN
The development of anthropomorphic robot hands are one of the main challenges in the creation
of robots that can execute various complex and useful tasks in a human environment.
The human hand can grasp and dexterously manipulate objects of various forms, and is modeled on a
tree-structured link mechanism with multi-degrees-of freedom, consisting of joints, muscles,
tendons, bones and so on. Many force receptors that endow the hand with a tactile sense exist
under the hand‘s skin. Based on a fusion between tactile recognition and the recognition
of grasped object’s position and orientation, a human manipulates an object by controlling
contact forces between the hand and the object. The human brain plays an essential role in
dexterous manipulation based on sensing and controlling. Using the human hand as a paradigm
provides a challenge in the design of robot hand mechanism involving a force and a distributed
tactile senor for the realization of dexterous manipulation by robots.
In this tutorial, the history of the development of anthropomorphic robot hands, the
distributed tactile sensor, the kinematics and dynamics of multi-fingered robot hands, hand
control methods, and future issues in the research and development of robotic hands are addressed.
Films on the experimental implementation an anthropomorphic robot hand called the Gifu Hand and a
multi-fingered haptic interface robot called HIRO II, which have been developed in Gifu
University will be shown. The HIRO II is a haptic
device that presents forces to five fingers of a
human operator who manipulate objects in a virtual
environment, which is an example of an application
of a robotic hand as a human-computer interface.

Design and Miniaturization of Ultra Wide Band
By Prof. Tan Phu Vuong
Ecole Supérieure d'Ingénieurs en Systèmes Industriels Avancés Rhône-Alpes, FRANCE
This tutorial introduces the design, the modelling
and the miniaturization of Ultra Wide Band (UWB)
antennas. Design of UWB antennas has to take into
account criterion that will be introduced.
Foremost those antennas have to exhibit constant
electromagnetic properties over a wide frequency
band. The design consists of finding a compromise
in-between minimal dimensions and acceptable
performances for the radiating diagram, efficiency
and dispersion. In addition UWB antenna should be
low-cost and compact.
This will lead the presentation to present
miniaturization techniques. Actual techniques
based on geometrical optimization studying the
surface current or the electric field created
in-between the antenna and its ground plane, and
the insertion of localised element, will be
introduced. Some examples of compact UWB antenna
design will be presented with their frequency and
Then the presentation will focus on UWB antennas
influences on communication systems. We will give
an introduction to characterization and modelling
techniques taking into account theoretical and
practical considerations. Finally the presentation
will introduce a new simulation method allowing
the integration of UWB antennas behaviours in the
simulation of a communication system. This last
point will be illustrated with some examples
taking into account several designs of UWB

8: Diversity Techniques in Wireless Communications
By Prof. Ha H. Nguyen1
and Prof. Tho Le-Ngoc2
1Department of Electrical and Computer Engineering, University of Saskatchewan, CANADA
2Department of Electrical and Computer Engineering, McGill University, CANADA
The main driving force behind the revolutionary development of wireless communications in the last
decade is the promise of mobility, flexibility and accessibility. While freedom is the main reason for the
users to go wireless, the key issue of the current and future wireless communication systems is to be able
to provide the end users with a more reliable, higher speed and multimedia data transmission.
The challenge is that such a goal needs to be achieved with limited power and spectral resources over the
unreliable wireless channel. A fundamental aspect of a wireless channel that makes the problem challenging
is that of the fading phenomenon, where the channel strength varies in time. How to deal with fading is
therefore central to the design of a wireless communication system.
The first part of the tutorial presents and discusses various diversity techniques to mitigate the
adverse effect of fading. Diversity techniques increase reliability by sending the same information
through multiple independently faded paths so that the probability of successful transmission is higher.
The techniques to be presented include (i) interleaving of coded symbols over time to obtain time
diversity, (ii) use of multiple receive and/or transmit antennas, via space-time coding, to obtain
spatial diversity, and (iii) coding over subcarriers in orthogonal frequency division multiplexing
(OFDM) systems to obtain frequency diversity. These diversity techniques are illustrated with examples
from existing wireless systems. The second part introduces an advanced multi-dimensional transmission
framework designed with bit-interleaved coded modulation and iterative decoding to exploit the diversity
and, at the same time, provide a large coding gain for a wireless communication system. The tutorial
concludes with a brief description of current research directions on cooperative diversity.
