Engineers working at Waltham, Massachusetts-based Fractal Antenna claim to have developed a device based on metamaterials that acts like an invisibility cloak for microwave radiation.
Built from belts of circuit boards festooned with fractal resonators, the device effectively 'slips' the microwaves around the cloaked object so the object is effectively invisible.

Plasma thruster
A ‘plasma thruster’ will be developed for launch into space within the next four years, as part of a prototype satellite.
It will be the first time in seven years that a piece of Australian hardware will be sent into space and the first time a satellite with a plasma engine will be tested.
It is to be developed as a result of a three-way collaboration between the SP3 Group, EADS-Astrium and the University of Surrey that was formally established in March this year.

Raytheon wins $19 million contract from USA for detection of land mines and tunnels.
Raytheon Company has received a $19 million contract from the Defense Advanced Research Projects Agency for development and demonstration of technology to detect and locate buried land mines and tunnels. n Raytheon's plan, a laser radar vibration sensor, or ladar vibrometer, would reveal hidden targets by measuring ground-surface vibrations and use electronic instructions for calculation and processing known as algorithms to interpret the information. The technology demonstrator would integrate the vibrometer with acoustic and seismic sources for field-testing on a moving vehicle.

Redefining Warfare's Electromagnetic Spectrum
In the electronic context, information warfare comprises two major branches – radiation warfare (RW) and data warfare (DW)." that are like yin and yang.
DW essentially involves obtaining control over opponents' processing, analysis and decision-making infrastructure in order to make it act in your interests rather than theirs. DW can range from infecting computers via well-known techniques such as internet-borne viruses, to inserting disinformation into a radio data stream through highly classified techniques with specialised equipment.

Metal Storm Completes 3GL Endurance Test
Metal Storm completed an endurance firing test launching 200 of its 40mm STORM40 ammunitions using its 3GL grenade launcher. Following the successful test, the company expects to begin production of the 3GL in 2010.
According to Dr Lee Finniear, CEO of Metal Storm Ltd., this feature provides users a critical advantage in an opening of an engagement; "in the first few seconds a squad equipped with 3GLs can unleash three times the number of 40mm grenades on the enemy. Whether in a planned attack, or in response to an ambush by the enemy, this firepower can be the decisive element in winning the firefight and saving our soldiers lives.” Finniear said.

TenCate's Add-On Armour Offers Soldiers Greater Protection
Danish engineers have developed a new add-on armour solution that effectively defeats explosive-formed projectiles generated from roadside bombs that often kill soldiers in Iraq and Afghanistan.
The armour is called Armourtex BM and designed for mounting on the outside of armoured vehicles, where it effectively protects the vehicle interior, which typically holds up to 10 soldiers. Moreover, the material has another indisputable advantage: It weighs much less than the steel plates that are the traditional form of armour protection.
