The Eighth International Kharkov Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves (MSMW'13) will be held in Kharkov, Ukraine on June 23-28, 2013. Within the symposium, the Workshop on Terahertz Technology (TeraTech'13) will be organized. During the symposium, a one-day workshop “Complex conductivity and wave symmetry of Fe-based superconductors” is also planned. These events will be sponsored by the National Academy of Sciences of Ukraine (NASU) Scientific Council on Radio-Physics and Microwave Electronics and A. Usikov Institute for Radiophysics and Electronics of NASU. IRE NASU has always been one of the major Ukrainian research organizations in this field. It was established in 1955 with the main tasks of developing the mm-wave vacuum sources, wave propagation and radars, and hot-plasma diagnostic systems for Tokamak controlled fusion machines; later it was involved in the development of in-orbit remote sensing and communication systems. Main collaborating organizations are the Institute of Radio Astronomy (IRA) of NASU, which branched off IRE in 1985 and leads research in the mm-wave radars and radio astronomy, Institute of Magnetism (IMag) of NASU and Ministry of Education and Science of Ukraine (MESU), which was founded in 1995 and performs research into modern problems of the physics of magnetism and magnetic materials, V. Karazin Kharkov National University (KhNU), the third oldest (since 1804) and highly reputed university in natural sciences in the Former Soviet Union (FSU), Kharkov National University of Radio Electronics (KhNURE), a technical university in Ukraine entirely in electronics and computers, three Ukrainian IEEE Joint Chapters, and the Ukrainian National URSI Committee. MSMW symposia were held several times in Kharkov since 1978 as regular FSU meetings on mm and submm waves and applications. It became a major event in this area and since 1991 it has been known as the International Kharkov Symposium - MSMW.
