Symposium1: Numerical Simulation and Visual Analytics of Nonlinear Problems
| Organizer | Atsushi Kamitani (Yamagata Univ.) |
| Co-organizer | Satoshi Tanaka (Ritsumeikan Univ.), Koji Koyamada (Kyoto Univ.), Seiichi Koshizuka (Univ. Tokyo), and Soichiro Ikuno (Tokyo Univ. Tech.) |
| Objective | Both the numerical simulation and the visual analytics have played an important role in the analysis of nonlinear problems arising in a wide variety of fields in science and engineering. For example, in solid-state physics, fusion engineering, and fluid dynamics, a number of high-performance numerical techniques have been proposed for solving nonlinear partial differential equations and they have contributed to the remarkable development of these fields. Moreover, visual analytics of complicated/large-sized data is indispensable for the analysis of the results obtained in numerical simulations. In this sense, the numerical simulation and the visualization should work closely together in the analysis of nonlinear problems. The aim of this symposium is to provide a forum for exchanging ideas and discussing recent developments in the numerical simulation and the visual analytics of nonlinear problems. |
Symposium2: Analysis of Optical Vortex Field and Applications
| Organizer | Hideki Kawaguchi (Muroran Inst. of Tech.) |
| Co-organizer | Hiroaki Nakamura (NIFS) |
| Objective | Optical vortex, which is classified in topological lightwaves of the first kind, reveals its original characteristics of spiral wavefront, propagation of orbital angular momentum, and so on. Since existence of the optical vortex was pointed out in 1992, the optical vortex has been investigated actively not only from scientific viewpoints but also on applications to various research fields, for example, large capacity optical fiber communication based on orthogonality of azimuthal vortex modes, optical tweezer based on orbital angular momentum of the vortex field, and so on. In addition, the concept of the optical vortex is expanded from the optical frequency to other frequency range such as X-ray, γ-ray and microwave. In this way, research activities of the optical vortex are still growing and expanding to various research area. The aim of this symposium is to provide a forum for exchanging ideas and discussing recent developments in the numerical simulation, measurement and experiment of the optical vortex. |
