A kind of coat, notably an invisible one. On each side glass roof stands off the historic walls exactly that tactful distance, to be considered not as an intrusion, but as a new piece of clothing complementing the existing “body”. The only additional thing is a smooth semi-transparent arc hanging over the constructivist pylons. Remarkably, this method fully justifies itself: both from the Leningrad highway and the opposite Petrovsko-Razumovskaya alley the renovated stadium visually has the same outline. To remain within the altitude demands, the architects designed a very shallow and saddle shaped roof, flattening it in the middle right over the field so that the outline of the new would not break into the existing city panorama too actively. So the roof is much larger than the stadium building itself and includes space along its two "long" sides - eastern and western facades. Leading in from the front of the apparatus is a wire that. For the experiment it is sandwiched between two horizontal aluminum plates, the bottom one 3 feet square and the top one 4 feet square. The last was possible due to thanks to the smart roof construction: it covers the entire amphitheater, slightly touching the existing platforms, and its console arches rest on columns placed along the exterior perimeter of the existing building. The object to be cloaked is just a small copper cylinder filled with black foam: 5 centimeters (2 inches) in diameter and 1 centimeter (0.4 inch) tall. Also in the historic stadium walls there will appear a "commercial periphery" - all kinds of shops, cafes, offices, football clubs - which then go to the underground level of the complex, and out of the monument territory. Harry Potter’s ‘invisibility cloak’ appears closer to reality as Canadian camouflage manufacturer Hyperstealth Biotechnology has applied for patents on its ‘.
For cloaking to work, the metal shapes stamped on the metamaterial must be smaller than the wavelength of the electromagnetic radiation that is aimed at them. The football field remains to be the centre of the entire, along its perimeter in the place of former athletic sector there are stands, instead of old stands there are lobbies. According to the Duke team, this experiment shows it should be possible to make an object invisible to the human eye as well, but there are major technical hurdles. We thought it essential to save the original football USSR arena.” This idea, in turn, determined the symmetrical layout of the renewed stadium. "We could have a totally formal approach here, we could leave a piece of the wall and demolish the rest, but we decided to keep the entire historical perimeter, location and the size of the old field - says Kuznetsov.
Sergei Kuznetsov the SPeeCH director and partner said one of the main criteria for the reconstruction work of the stadium was the delicate approach to the monument.
