Designing Microwave Devices From Scratch Using Computer Simulations
For decades, the fundamental design of microwave devices, such as antennas for mobile communication and waveguides used in radars, has essentially relied on the inventiveness of a professional designer.
NOEMA Discovers "Eye Of Medusa" Star Formation
NOEMA (Northern Extended Millimeter Array), the most powerful millimetre radio telescope of the Northern Hemisphere, has unveiled its first astronomical image: a unique and spectacular view of a previously unknown region of extreme star formation in the ‘Medusa merger’ – a luminous collision of two galaxies at more than 100 million light years from Earth.
ALMA Weighs Black Hole With 140x Sun's Mass
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have measured the mass of the supermassive black hole at the center of NGC 1097 -- a barred spiral galaxy located approximately 45 million light-years away in the direction of the constellation Fornax. The researchers determined that this galaxy harbors a black hole 140 million times more massive than our Sun.
Isola’s Astra MT Materials Successfully Evaluated With Freescale Radar ICs
The demonstration example, using Freescale radar ICs on Astra MT's advanced thermoset dielectric material for millimeter-wave automotive radar, will be demonstrated at the International Microwave Symposium (IMS) 2015. The , and will highlight Astra MT material's reliable electrical performance in wide field-of-view radar applications for automotive systems.
New Spaceship Antenna Could Prevent Radio Blackout During Re-Entry
Scientists from the Harbin Institute of Technology in China have proposed a new way to maintain communication with spacecraft as they re-enter the atmosphere. The approach might also be applied to other hypersonic vehicles such as futuristic military planes and ballistic missiles.
