The third International Conference „Ultrawideband and Ultrashort Impulse Signals» (UWBUSIS’06) was held in the beautiful Crimea city of great ancient history – Sevastopol, Ukraine, from September 18 till 22, 2006. The venue of the conference, this time, was one of the largest technical university of Ukraine, Sevastopol National Technical University. The reports about the previous meetings can be found in the IEEE Antennas and Propagation Magazine, December 2002, pp. 92-94, February 2005, pp. 193-196.

The conference provided the international forum for discussing recent advances in theoretical investigations, computer modeling, experiments, technology, and applications of ultrawideband and ultrashort impulse signals. The conference first started as a workshop in 2002. It was organized due to joint efforts of Kharkov IEEE Chapter and Karazin Kharkov National University. In 2002 we met 47 participants. Since then, the number of participants and scientists interested in UWB problems continually grows. The second UWBUSIS workshop (2004) attracted more than 100 participants and 97 contributed papers. This year the Technical Program Committee had invited 20 papers and accepted 114 more contributed ones from Ukraine, Russia, USA, China, Poland, Australia, Lithuania, the Netherlands, Denmark, Ireland, Germany, United Kingdom and Mozambique. The Proceedings of the UWBUSIS’06 were prepared very professionally. One volume Proceedings include 114 papers of 384 pages.

The Conference was organized under the direction of Professor Nikolay Kolchigin from V.N. Karazin Kharkov National University and Professor Yakov Shifrin from Kharkiv National University of Radio Electronics. The main organizers of the conference were as usually Kharkov IEEE Joint Chapter and Karazin Kharkiv National University, which is a well known academic centre of East Ukraine founded as early as in 1804.

Co-organization and sponsorship of the UWBUSIS’06 Conference was fulfilled by the following organizations: Sevastopol National Technical University, European Microwave Association EuMA, Institute of Electrical and Electronics Engineers IEEE, AP-S IEEE, Kharkiv National University of Radio Electronics, National Antenna Association of Ukraine, Radio Astronomy Institute of NASU, Ukraine URSI Committee, Institute of Radio Physics and Electronics of NASU, National Technical University “KPI”, Scientific-Production Company “TERA” (Kiev), Ukrainian Science Academy SMF “Institute of automatic system”.

The UWBUSIS’06 Conference was organized as a plenary session, and four parallel sessions for contributed papers (fig. 1, 2). On the sessions the scientists were able to listen the brilliant reports of the famous specialists in the area of ultrawideband signals and in adjacent areas, namely: Prof. Carl E. Baum (USA), Prof. Immoreev (Russia), Prof. L.Yu. Astanin (Russia), D. M. Vavriv (Ukraine), Prof. Ira Kohlberg(USA), Prof. Felix Yanovsky (Ukraine), Prof. Boris Levitas (Lithuania), Prof. Robert Gardner (USA), Prof. Victor Kravchenko (Russia), Prof. S.L. Prosvirnin (Ukraine), Prof. A.N. Titov (Russia), Prof. Yu.K. Sirenko (Ukraine), Prof. Robert McMillan (USA), Prof. Konstantin Lukin (Ukraine), Gordon Boezer (USA), Prof. A.G. Nerukh (Ukraine), Dr. Genadiy P. Pochanin (Ukraine) (fig. 3-8).

The Conference provided wide international forum for discussing recent advances in ultrawideband and ultrashort impulse signal problems on the following subjects:

Theoretical investigations, numerical simulations;
Generation, radiation, and receiving;
Electromagnetic compatibility;
Propagation and scattering in natural and artificial materials (complex media, radio absorbers, bio materials, nano-structures, meta-materials etc.);
Applications (communication, radar, GPR, medicine, etc.)
Electromagnetic metrology;

Each day we had a lot of interesting presentations and active discussions. As for me the most interesting subjects at the UWBUSUS were presented by Prof. Immoreev on applied applications of UWB technology, by Prof. Astanin on some aspects of near-field UWB polarization characteristics and waveforms analysis and presentation of Yukhanov Y.V. and group authors from Taganrog on suppressing sidelobes for UWB arrays using nonplanar antennas arrangement.

A special gratitude should be expressed to EuMA for sponsoring the young scientist contest that undoubtedly helped promoting UWB among new scientists generation. Members of the award committee: Prof. F. Yanovsky, Prof. Ya. Shifrin, Prof. N. Kolchigin, Prof. Yu. Gimpelevich, Ph.D. G. Pochanin, with section chairs: Prof. Carl Baum, Prof. A. G. Nerukh, Prof. K. Lukin, Ph.D. A. N. Titov, Prof. V. V. Ovsyannikov, Prof. M. I. Andriychuk considered presentations of 17 young scientists submitted for the contest. The committee came to the following decision:

1st award is given to Alexander Butrym for presentation “Charge transport by a pulse E-wave in a waveguide filled with conductive medium” (fig. 9);

Two 2nd awards were given to Yunus Smailov for presentation “Mathematical model of the microwave transducer of the complex reflection coefficient” and to Nataliya Sakhnenko for presentation “Isolated 2D plasma resonator illuminated by transient source” (fig.10);

Two 3rd awards were given to Vadim Ruban for presentation “Symmetric sampling gate with stored charge dumping” and to Eduard Ziganshin for presentation “Pulse-Doppler UWB radar” (fig.11,12).

Organizing Committee arranged a good culture program. The banquet and welcome party were well organized to gather all the participants in a friendly, relaxed, and warm atmosphere. Igor Vetrov and Yurij Gimpelevich, representatives of Sevastopol National Technical University, nominated Nikolay Kolchigin to warrant officer and presented him a sailor’s cap on the banquet. Carl Baum presented a music box playing his melody to Yakov Shifrin (fig. 13). The participants had the opportunity to establish very important scientific contacts and discuss what problems will be of interest in future.

During the break day in the conference work the participants had opportunity to enjoy beauty of the Black Sea, walk around the ruins of ancient Greek city Chersones, Sevastopol’s sightseeings, and join guiding tours to Vorontzov’s Palace, Massandra Palace, Yalta and Balaklava cities (fig. 14).

I would like to acknowledge the efforts of professors N. Kolchigin, Ya. Shifrin, and all the members of program and local organizing committees for successful organizing the meeting at high technical and scientific level, and for impressive culture program. The atmosphere and style of UWBUSIS’06 can be felt from some interesting photos (fig. 7,8, 16-18).

We have gained a lot of pleasant memories at Conference about all of its aspects: scientific discussions, meetings with colleagues, a few days of stay in the nice city on the coast of the warm sea.
