For over 10 years, Micromag has been working with defence industry customers which sole focus is on Radar Absorbing Materials for stealth applications. Micromag's high quality and flexibility to tackle unique projects, applicable to multiple operating platforms, makes us a reference company in the defence market. Our technology provides an excellent performance for Air, Land and Sea applications, reducing significantly the Cross Section of any element that it is applied to.

This amazing solution has significant advantages in comparison with other technologies. Firstly it dramatically reduces the add-on weight which is in the order of grams versus the kilograms offered by other technologies. Moreover, they do not have such a broad operating performance. This reduction is critical for certain aviation applications in which aero-navigability and weight are deeply related. Secondly as it is embedded within regular paints or other materials, such as, fiber glass and foams, it allows its application not only on new elements but also in existing platforms. Last but not least, it offers a unique durability, in the order of years, significantly decreasing the operations costs.

Tabarca: Patrol Ship (Supported by Spanish Navy)

As a first commercial reference the technology was proven with the support of the Spanish Navy in 2009 by applying it to a Patrol ship with astonishing results.  There was an amazing reduction in the RCS. This reduced RCS yields significant advantages, both, in the Advantage Factor and in the Anti-Missile effectiveness.

Latest simulations from the Spanish Navy conclude that, on a geometrical simulation scenario, the increase in survivability raises from 45 % to 90 %, in the best case.

Alusafe: Operating Unit of the National Homeland Security in Spain

Another important commercial reference in Micromag’s endeavour ocurred in 2011 with the application of our technology to an operating unit of the National Homeland Security Agency in Spain. This unit is used to Control Borders, drug Trafficking and Special Operations.

We proved, once again, the effectiveness of our technology providing significant operating advantage. The vessel was only detected by the enemy radar some 55 seconds before reaching the target. “It disappeared into the sea” “With this signal on the radar display it could be a wave” were some of the radar operators’ comments during the RCS measurements.


CIVIL MARKET

Micromag’s unique R&D skills allow to use all of our knowledge, built from the defence market applications, to provide the best possible solutions to the needs of civil industry customers. At Micromag we offer a broad range of products relative to microwave absorber technology, as well as, sensors, all in custom configuration.

Design of radar absorbing wind turbine blades (the project is being performed jointly  with INDRA Systems S.A., the market leader supplier of radar solutions)

Energy and the environment have been rising rapidly up government agendas in recent years, having a policy of encouraging the development of renewable energy sources. One such renewable energy is the power available from the wind as an alternative to fossil fuels. For this reason wind farms installations have steadily increased in number in the last fifty years. The increased population of wind farms pose interference with radar signals problems.

It is known that rotating blades can, in some combinations with orientation and blade angle, cause significant unwanted doppler returns to the iluminating radar creating confusion for radar operations. The nature of this signal makes them very difficult to filter within the radar software.

Several sectors might be affected, including the different types of radar used for Air Traffic Control, weather monitoring and marine navigation aids. There is, thus, a conflict of interest between the desire to encourage wind farm development and the desire to maintain the safety of the people.

Many cases are known where the presence of a wind farm adjacent to an airport is causing problems. Detecting an echo caused by wind turbines can distract the air traffic controller and reduce the effectiveness of the radar by masking genuine aircraft returns.

The aim of this project is to demonstrate that it is possible to reduce the RCS of blades incorporating Micromag’s radar absorbing material not only in new wind farms but also in existing ones. In the first case the solution lies in using fiber glass treated with our technology without compromising structural integrity at acceptable cost and quality. In case of existing platforms the objective is to treat the blade surface with Micromag‘s technology.



Presence DetectionSystem

Micromag’s working philosophy is not just to provide a selection of standard products; our ability is to offer individual solutions to each of our customers, understand their needs and use our know-how to find the best solution. Our capability to adapt our technology to custom requirements is demonstrated not only by finding the best solution to each individual situation but also by finding new applications to our well known stealth technology.

This is the case of one of our recent projects: the implementation of a Perimeter Detection System using Micromag’s metallic fibers. The goal of this system is to achieve better performance, easier installation and lower cost than existing solutions.

Micromag’s presence sensor is an invisible detection system because it is suitable for installation under the surface to be monitored. How does it work? The system includes a capacitive sensor comprising two aluminum electrodes and our metallic fibers embedded within flexible foam as the separating dielectric. The composite has a very different dielectric constant thanks to the inclusion of metallic microfibers, which increases significantly the sensitivity of the sensor.

When a certain pressure is exerted, the distance between electrodes is reduced and the fibers relative concentration in the material is increased. It results in changes in the capacitance that can be monitored and converted into weight changes, detecting for example if it is an animal, a child or an adult.
