A filter that enhances the power of communications satellites


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: Kick-off for a new era of precision astronomy

The MICADO camera, a first light instrument for the European Extremely Large Telescope (E-ELT), has entered a new phase in the project: by agreeing to a Memorandum of Understanding, the partners in Germany, France, the Netherlands, Austria, and Italy, have all confirmed their participation. Following this milestone, the project's transition into its preliminary design phase was approved at a kick-off meeting held in Vienna. Two weeks earlier, on September 18, the consortium and the European Southern Observatory (ESO), which is building the telescope, have signed the corresponding collaboration agreement.

As the first dedicated camera for the E-ELT, MICADO will equip the giant telescope with a capability for diffraction-limited imaging at near-infrared...

Im Focus: Locusts at the wheel: University of Graz investigates collision detector inspired by insect eyes

Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.

Im Focus: High-speed march through a layer of graphene

In cooperation with the Center for Nano-Optics of Georgia State University in Atlanta (USA), scientists of the Laboratory for Attosecond Physics of the Max Planck Institute of Quantum Optics and the Ludwig-Maximilians-Universität have made simulations of the processes that happen when a layer of carbon atoms is irradiated with strong laser light.

Electrons hit by strong laser pulses change their location on ultrashort timescales, i.e. within a couple of attoseconds (1 as = 10 to the minus 18 sec). In...
