Invisibility Cloak to Improve Military Operations

 

A team of scientists from the University of California, San Diego (UCSD) have developed a material that resembles an invisibility cloak. The material could change the face of military operations and would allow weapons and maybe even military personnel to function while undetected. UCSD scientists have tested the “first effective dielectric metasurface material—an ultra-thin, … [Read more...]

X-ray Prototype Uses Electromagnetic Waves to See Through Buildings

 

A team of researchers from the University of Sydney have developed an X-ray prototype that allows people to see through walls. The prototype uses electromagnetic waves to bounce information off walls, according to researchers. Successful trials of the device have just concluded. "We can then process the waves to retrieve the information we want. Then we reshape the wave so … [Read more...]

Scientific Inconsistency Noted in Electromagnetic Theory Breakthrough

 

The results of a study where scientists claim they found a missing link in electromagnetic theory, published by researchers from Cambridge University, was recently called into doubt. Scientists from ITMO University, Australian National University and Aalto University questioned this claim, according to Phys.org. “The study, conducted by the British scientists, was presented as … [Read more...]

Magnetic Field Cloak to Assist MRI Scanners and Medical Industry

 

Scientists from the Autonomous University of Barcelona have created a magnetic field cloak, or ‘wormhole,’ which could lead to better MRI scanning. “The wormhole allows a magnetic field to be transported across space but it is not the kind of cosmic tunnel popularised by science fiction. Rather, the magnetic field at one end of the wormhole appears at the other end as an … [Read more...]

New Metamaterial Yields Invisibility for Aircraft and Drones

 

Electrical engineers from the University of California have created a new ultra-thin metamaterial that could provide a cloaking device and make UAVs (Unmanned Aerial Vehicles) invisible. The new material creates invisibility and leaves no electronic, infrared or visual signatures for enemies to detect. The new design uses “an ultra-thin Teflon substrate, studded with … [Read more...]

3D Printing Can Add Circuitry

 

Researcher Michael Perrone is currently testing a prototype of one of the world’s most advanced 3D printers, which was built by a startup company known as Voxel8. The 3D printer is not on the market yet, but it can produce small objects out of plastic while simultaneously adding circuitry to them. The printer was produced last month in a lab at Harvard University. During … [Read more...]

High-tech Highways Could Charge Electric Cars While Driving

 

The United Kingdom is currently testing technology that would allow high-tech highways to recharge electric cars as users are driving. “The U.K. has already tested a bunch of different approaches to this technology and identified versions that work and are ready to manufacture. In basic terms, the system has power lines connected to coils under the surface of a road, which … [Read more...]

High Power Coaxial Limiters Handle up to 200 Watts

 

Fairview Microwave Inc. announces a new family of broadband, high power coaxial limiters that protect sensitive components and RF receivers that are close to high power signals. Depending on the model, the limiters operate on frequencies ranging from 0.5 GHz to 40 GHz. The limiters also offer seven different design options, a low leakage power of 10 to 15 dBm and limited … [Read more...]

Electromagnetic Catapult Successfully Installed on Aircraft Carrier

 

The Navy’s new electromagnetic catapult, the Electromagnetic Aircraft Launch System, (EMALS) has successfully been installed on the USS Gerald R. Ford, replacing the steam catapults previously used to launch aircraft. Because EMALS yields less maintenance, more control, more reliability and a lighter weight, the Navy decided it will be used on all future aircraft carriers in … [Read more...]

African Village Burning Rituals Help Identify Reason for Magnetic Field Weakening

 

A team of scientists has reported that ancient village burning rituals that took place during the Iron Age have provided evidence of what could have possibly caused the weakening of the magnetic field in South Africa. Scientists discovered that a hot and dense rock 2,000 miles beneath the surface that is 4 miles wide is the cause of Africa’s magnetic field weakening. “The … [Read more...]
