Amana Radar Range Microwave
- A measurement of the distance an object can be seen by radar based on the height of the antenna, the height of the object and atmospheric bending of the radar beam.
- kitchen appliance that cooks food by passing an electromagnetic wave through it; heat results from the absorption of energy by the water molecules in the food
- An electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation. Microwaves are used in radar, in communications, and for heating in <em>microwave</em> ovens and in various industrial processes
- cook or heat in a microwave oven; "You can microwave the leftovers"
- a short electromagnetic wave (longer than infrared but shorter than radio waves); used for radar and microwave ovens and for transmitting telephone, facsimile, video and data
- Amaná is a municipality and village in La Rioja Province in northwestern Argentina.
- Amana – perennial. The Hebrew margin of 2 Kings 5:12 suggests another reading of Abana, a stream near Damascus.
- The Amana Corporation is an American brand of household appliances. It was founded in 1934 by George Foerstner as The Electrical Equipment Co. in Middle Amana, Iowa to manufacture commercial walk-in coolers.

Stealth design SU-35 aircraft Hostile radar range cut on Su-35s
US and European aircraft manufacturers have used specially developed materials to reduce the RCS of basically non-stealthy aircraft for many years. Notable examples include the Have Glass and Have Glass II modifications to the F-16. However, Russian work in this area was undisclosed until ITAE researchers presented a paper to a conference on stealth in London in late October 2003, which was organized by the International Quality and Productivity Centre. According to the ITAE presentation, Russian researchers have developed mathematical tools that can calculate scattering from complex configurations, such as an Su-35 carrying a full external missile load, by breaking them down into small facets and adding the effects of edge waves and surface currents. The antennas are modelled separately and then are added to the entire RCS picture.
"A problem of huge size" is how the researchers describe the Su-35 inlet, with a straight duct that provides direct visibility to the entire face of the engine compressor. The basic solution has been to apply ferro-magnetic radar absorbent material (RAM) to the compressor face and to the inlet duct walls, but this involves challenges. The researchers note: the material cannot be allowed to constrict airflow or impede the operation of anti-icing systems and must withstand high-speed airflows and temperatures up to 200°C. The ITAE team has developed and tested coating materials that meet these standards. A layer of RAM between 0.7mm and 1.4mm thick is applied to the ducts and a 0.5mm coating is applied to the front stages of the low-pressure compressor, using a robotic spray system. The result is a 10-15dB reduction in the RCS contribution from the inlets. The modified Su-35 also has a treated xxxxpit canopy which reflects radar waves, concealing the high RCS contribution from metal components in the xxxxpit. ITAE has developed a plasma-deposition process to deposit alternating layers of metallic and polymer materials, creating a coating that blocks radio-frequency waves, is resistant to cracking and crazing and does not trap solar heat in the xxxxpit. The plasma-coating process is then carried out robotically in a 22 m3 vacuum chamber.
ITAE and its partners have also developed plasma-type technology for applying ceramic coatings to the exhaust and afterburner. The conference video also showed the use of hand-held sprays to apply RAM to R-27 air-to-air missiles. ITAE has studied at least three techniques for reducing the RCS contribution of the radar antenna, in addition to the simplest method of deflecting the antenna upwards and treating or shrouding other components. One of these is to design a radome that can be switched from RF-transparent to RF-reflective. The interior of the radome would be coated with a cadmium sulphide or cadmium selenide thin-film semiconductor material which changes conductivity when illuminated with visible or ultra-violet light. However, the problem of making such a film has not been solved.
A second technique that is also described in Western literature is to place a frequency selective surface screen in front of the antenna. This is a foil-like metal screen etched with small apertures which allow RF energy to pass within a narrow waveband, corresponding to the radar’s own operating frequency. This reduces RCS, according to ITAE, but at the expense of radar performance. However, ITAE has flight-tested a more exotic technology: the use of a low-temperature plasma screen in front of the radar antenna. The screen hardware is mounted in front of the antenna and is transparent to the radar when switched off. When activated, the screen absorbs some incoming radar energy and reflects the rest in safe directions over all RF bands lower than the frequency of the plasma cloud. It switches on and off in tens of microseconds, according to ITAE. In principle, this is the same as the ‘plasma stealth system that was reportedly developed by the Keldysh Scientific Research Center (also part of the Academy) in 1999.
At the time, it was claimed that the system, using a 100kg generator, could reduce the RCS of any aircraft by two orders of magnitude, or 20dB. ITAE has not attempted to develop a whole-aircraft system, but researchers expressed the view that it would be difficult to apply except to a high-altitude, low-airspeed aircraft because the airstream would dissipate the plasma faster than it could be generated
