New lens device will shrink huge light waves to pinpoints
Manipulating light waves, or electromagnetic radiation, has led to many technologies, from cameras to lasers to medical imaging machines that can see inside the human body. view more (2007-07-13)
Scientists closer to making invisibility cloak a reality
J.K. Rowling may not have realized just how close Harry Potter's invisibility cloak was to becoming a reality when she introduced it in the first book of her best-selling fictional series in 1998. Scientists, however, have made huge strides in the past few years in the rapidly developing field of cloaking. Ranked the number five breakthrough of... view more... (2009-03-06)
'Invisibility cloaks' could break sound barriers
Contrary to earlier predictions, Duke University engineers have found that a three-dimensional sound cloak is possible, at least in theory. view more (2008-01-10)
Catching the wave — Researchers measure very short laser pulses
Scientists have perfected a technique for very accurately measuring and controlling the electromagnetic waves within some of the shortest laser pulses ever made, says new research published today. view more (2006-12-04)
Theoretical blueprint for invisibility cloak reported
Using a new design theory, researchers at Duke University's Pratt School of Engineering and Imperial College London have developed the blueprint for an invisibility cloak. view more (2006-05-26)
American distinction for Professor De Hoop
Prof.Dr.Ir. (Adrianus) A.T. de Hoop, retired professor of TU Delft (the Netherlands), will receive the 2001 Heinrich Hertz Medal from the Institute of Electrical and Electronics Engineers (IEEE) in the United Stated on 23 June. This distinction has been awarded to him for "his fundamental contributions to the theory of reciprocity and to the... view more... (2001-06-20)
Beyond the looking glass
While the researchers can't promise delivery to a parallel universe or a school for wizards, books like Pullman's Dark Materials and JK Rowling's Harry Potter are steps closer to reality now that researchers in China have created the first tunable electromagnetic gateway. view more (2009-08-13)
Taming Tiny, Unruly Waves for Nano Optics
Nanoscale devices present a unique challenge to any optical technology - there's just not enough room for light to travel in a straight line. view more (2007-10-09)
Visualizing atomic-scale acoustic wavesin nanostructures
Acoustic waves play many everyday roles - from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of nanostructures such as LED lights. view more (2008-07-07)
Discovery at UAB brings us nearer to making the dream of invisibility true
A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light - very low frequency electromagnetic waves - by making the inside of the magnetic field zero but not altering the exterior field. view more (2009-07-08)
Smallest Nanoantennas for High-speed Data Networks
More than 120 years after the discovery of the electromagnetic character of radio waves by Heinrich Hertz, wireless data transmission dominates information technology. view more (2009-10-21)
Large earthquakes may broadcast warnings, but is anyone tuning in to listen?
Like geological ninjas, earthquakes can strike without warning. But there may be a way to detect the footfalls of large earthquakes before they strike, alerting their potential victims a week or more in advance. A Stanford professor thinks a method to provide just such warnings may have been buried in the scientific literature for over 40 years. view more (2007-12-13)
Making monster waves
Rogue waves-giant waves that spring up suddenly and tower over the seas around them-have inspired physicists to look for an analogue in light. view more (2009-10-20)
Scientists identify origin of hiss in upper atmosphere
Scientists have solved a 40-year-old puzzle by identifying the origin of the intense radio waves in the Earth's upper atmosphere that control the dynamics of the Van Allen radiation belts - belts consisting of high-energy electrons that can damage satellites and spacecraft and pose a risk to astronauts performing activities outside their... view more...

Measure the speed of light using Milky Way Stars®
Nothing travels faster than light - it only takes 8 minutes for it to reach the Earth from the nearest star, the Sun, which is 150 million kilometres away. Now anyone can measure this speed - with chocolate stars and a microwave oven! The experiment is described on a new Institute of Physics web resource for teachers about fun physics... view more...

T-ray breakthrough could make detecting disease far easier
A breakthrough in the harnessing of 'T-rays'-electromagnetic terahertz waves-which could dramatically improve the detecting and sensing of objects as varied as biological cell abnormalities and explosives has been announced. view more (2006-11-03)
Earth's core rotates faster than its crust, scientists say
Scientists have ended a 9-year-old debate by proving that Earth's core rotates faster than its surface, by about 0.3 to 0.5 degree per year. view more (2005-08-26)
A sonic boom in the world of lasers
It was an idea born out of curiosity in the physics lab, but now a new type of 'laser' for generating ultra-high frequency sound waves instead of light has taken a major step towards becoming a unique and highly useful 21st century technology. view more (2009-06-18)
Ready to go: mobile terahertz devices
Terahertz waves, which until now have barely found their way out of the laboratory, could soon be in use as a versatile tool. Researchers have mobilized the transmitting and receiving devices so that they can be used anywhere with ease. view more (2008-04-09)
No increased risk of brain cancer from electromagnetic fields
Exposure to electromagnetic fields does not increase the risk of developing a brain tumour, finds a study of electricity industry workers, reported in Occupational and Environmental Medicine. Researchers from the Institute of Occupational Health at the University of Birmingham assessed causes of death among just under 84,000 workers employed in... view more... (2001-09-07)
