Combining advanced laser technology in a new way, physicists at the National Institute of Standards and Technology (NIST) have produced signs that are more pure and more stable than those produced with conventional electronic sources. The result could be very useful to improve the stability and resolution of radar, communication and navigation systems as well as certain types of atomic clock.
Described in the latest issue of the journal Nature Photonics , the apparatus of the NIST low noise is a new application of optical frequency combs, ultrafast laser-based tools for accurate measurements of optical frequencies.

In his thesis New techniques for the synthesis of microwave devices based on mode coupling theoryIsrael Arnedo Gil, Telecommunication Engineering from the Public University of Navarra (UPNA) has proposed a new method to design microwave filters, devices essential for controlling the amount of energy and time it takes to get from one point to another system.
What has in common with a microwave radar, satellite communications, mobile or wireless? All of them use in microwave and millimeter wave operation. In his doctoral thesis, “New techniques for the synthesis of microwave devices based on mode coupling theory”, Israel Arnedo Gil, Telecommunication Engineering from the UPNA, has proposed a new method to design microwave filters, devices essential to control the amount of energy and time it takes to get from one point to another system. His research has helped improve certain applications and obtain an international patent exploitation.
Microwave circuits and millimeter waves are used to generate, process and detect electromagnetic signals at a given frequency range, between 1 GHz and 300 GHz. Its applications are diverse: the radar (location of people, weather forecasting, air traffic control or ground), the transmission of information (telephony, television, internet or data) using microwave terrestrial links (repeater systems) and spatial (satellite communications), wireless communications systems, food and heating materials and high-sensitivity receivers for radio astronomy.
