The ‘world’s largest IT project’ — a system with the power of one hundred million home computers — may help to unravel many of the mysteries of our universe: how it began, how it developed and whether humanity is alone in the cosmos.

Design and Simulation of Phased Arrays For Radar/Aerospace Applications
Phased array antenna systems, which use sets of two or more antennas, offer improved performance over single antennas and are well-known for their usefulness in radar and aerospace applications. Communication system design software supports the design and analysis of phased arrays, as well as their implementation in a system of antenna elements, power divider/combiners, phase shifters, and other typical components. This article examines how software can be used to simulate both small and large phased arrays in typical configurations.
In order to consider all potential designs and quickly produce antennas that fit their specifications, engineers choose to use antenna synthesis. In addition to synthesis tools, full-wave 3D simulation can complement synthesis tools and allow designs to be checked and fine-tuned for effects that cannot be accounted for analytically. This article explains how the Antenna Magus, an antenna synthesis tool, and CST MICROWAVE STUDIO®, a full-wave 3D electromagnetic simulation program, are used to design a planar phased array.
It is necessary to be compliant with all EMC standards in order to release a product to market. Since EMC engineering is traditionally only used in measurement, EMC compliance ends up being considered late in the design process. If problems arise at this late stage, correcting them can become expensive, especially if multiple prototype iterations are required. For this reason, simulation is used to allow EMC compliance to be analyzed in greater depth in the earlier stages of the design process.
Many sensor applications rely heavily on the electromagnetic field and its accurate measurements. By using the CST STUDIO SUITE®, sensors are able to easily simulate electromagnetic fields through a wide range of Finite Element Methods (FEM) and other complementary simulation methods. This article walks through the use of the CST STUDIO SUITE® in virtual prototyping, field visualization, optimization, and modeling and CAD data import.
Today’s advanced military systems – including phased array radar, communications systems and EW sensors – require high-frequency, high-bandwidth, high-power, high-efficiency devices. These applications are where GaN differentiates itself from other materials. GaN devices can operate at higher bias voltages, which provides several advantages at both the system/subsystem and circuit level, leading to a proportional decrease in current requirement for the circuit. The bottom line: GaN improves the system-level trade-off of size, weight, and power.

Radar Guards Against Space Debris
Space debris poses a growing threat to satellites and other spacecraft, which could be damaged in the event of a collision. A new German space surveillance system, schedu- led to go into operation in 2018, will help to prevent such incidents. The tracking radar is being developed by Fraunhofer researchers on behalf of DLR Space Administration.
