"Currently, the radio wave spectrum is very much noisy in the world: for example, we have about 20 television channels, cable ones not included, mobile communications, ad hoc communication channels – (FSB, MVD, Emergency Control Ministry), satellite communications, Wi-Fi in every home, Bluetooth in the car. The problem is that all these public frequencies must not influence at all, for example, the air navigation system and other airborne radar systems on aircrafts. To deal with it special filters frequencies are required "- Andrey Leksikov, the research fellow of the L.V. Kirensky Krasnoyarsk Institute for Physics of RAS says about an idea of the project born in the walls of his laboratory of electrodynamics and microwave electronics and dedicated to "the development and manufacture of miniature bandpass filters for satellite communications systems with suppression in the stop band of more than 100 dB". The project was launched in June this year with the support of the Federal Target Program "Research and development on priority directions of scientific-technological complex of Russia for 2014-2020" and is primarily focused on the development of components for modern communication systems.

 
The laboratory of electrodynamics and microwave electronics has been dealing with the theme of the filters from the 1990s; in particular, special instrument was designed in the laboratory to produce them without expensive photolithography (if too high resolution is not required).

The main task of the laboratory involved in the development, is to reduce the size and improve the performances of various communication systems, which are used in civil and military field. "All the electronics eventually decreas in size, everything become compact and portable, but the filters still occupy much space in specialized electronics, - the young scientist says about what the FTP project should result in. - Our know-how permits to reduce the dimensions of the filters 100-fold, which in turn should lead to a significant reduction in size of device.

For example, on the basis of what we have already modeled, the weight of brigade radios can be reduced two-fold".

In addition, a new type of device, developed in Krasnoyarsk, allows you to extend the so-called "band boom" – i.e. the frequency band in which the device will not be affected by any "parasitic" signals.

To the present day, the standard band consist of two-three resonant frequencies, and Krasnoyarsk scientists generated a year ago an idea of the device, in which the band is expanded up to 30-40 resonant frequencies (which may suppress interferences down nearly 10 billion fold).

The know-how of the project was proposed by another young scientist and senior researcher at the Laboratory of electrodynamics and microwave electronics whose name is Alex Sergeantov. He tested his model on the computer first obtaining the desired effect and then the laboratory team began to experiment with "hardware". Today, the guys are trying to improve the characteristics obtained – to change the number of elements inside the cavity and to change its topology.

The Laboratory of electrodynamics and microwave electronics has been dealing with the topic since 1990s: Boris Belyaev, the current head of the laboratory, is hold for the ancestor of this field in Russia by his collegues. But the idea to launch a joint case came to the scientists after a meeting with representatives of the Krasnoyarsk radiofactory SPE "Radio" and Academician M.F. Reshetnev JSC "Information Satellite Systems" that have been buying most of the electronic components in Europe and the USA for a long time. But now all of them work together and are looking forward to achieve the import substitution via implementation of the project and to develop their own technology basis and develop the product better than that produced abroad.

"Foreign developers are ahead of us in technologies – Leksikov says. - But from as far as science is concerned the characteristics that we obtain, are much better in many sense, so we actively publish results in international journals abroad, and there are no any problems with these publications". Just this year the article on the project was published in the "Letters to the Journal of Technical Physics" magazine and another one is already being peer reviewed - in the American Journal IEEE Microwave and Wireless Components Letters.

"Ignoring publishing is impossible, - Andrey Leksikov says. - At the time, we have missed the right moment: we only published in Russian press, defended Russian patents, and other people have been internationally recognized in this niche by the moment, so we should make a sort of breakthrough ".

According to the developers, nobody in the world produces now the devices with characteristics, which may appear due to their project at the L.V. Kirensky Institute of Physics. "This is despite the fact that everything we do, is done on pure enthusiasm, because we do not even have the LTCC technology in our laboratory, and we operate things that were created 20 years ago, - Leksikov complains. - But recently, our «Radio» industrial partner have bought the necessary equipment, and we are confident that our idea plus their technology will result in a real breakthrough".
