A filter that enhances the power of communications satellites

04.02.2005


Researchers at the Public University of Navarre are designing and developing a filter that enhances the power of communications satellites for the European Space Agency. The filter enables the reduction, by a factor of a million, interference produced by what is known as the “Field Emission Effect”.



The work developed by the Navarre researchers is in its final stages and its results have been satisfactory, given that the filter devised enables the reduction of interference produced by a factor of a million and avoids the possible destruction of components. These results may form a new standard for the aerospace industry given the significant saving in size and weight - vital factors in the sector.

The project entitled “ESTEC contract High Power Filter” has been concluded successfully after nearly two years of work.


Patent application

More precisely, the European Space Agency was trying to resolve the problems produced in communications satellites by what is known as the “Field Emission Effect”. Communications satellites need to emit with more power both for signal quality reasons as well as because of the need to cover wider geographical zones. The problem is when a satellite emitter goes beyond the power threshold, an effect that deteriorates the components and the aerials arises. This is what we technically know as the Corona and Multipactor Effect. Its origin lies in the fact that high power levels produce very intense electromagnetic fields. These very intense fields in very low-pressure conditions generate an avalanche of electrons on to metals that can become destructive and cause losses in heavy investment.

The project developed by researchers at Public University of Navarre has worked on the design of a filter that eliminates this effect, enabling work at the desired power levels.

The results have been so positive that the research team, together with the ESA, have applied for an international patent for the filter for its commercialisation.

Im Focus: Worldwide Success of Tyrolean Wastewater Treatment Technology

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.

The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...

Im Focus: Computational high-throughput screening finds hard magnets containing less rare earth elements

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.

The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
