New diffraction phenomenon of acoustic waves. A novel asymmetric diffraction has been achieved using a nano-patterned array of ferromagnets. This demonstration arises from a unique interaction between ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 250, No. 1263 (Apr. 7, 1959), pp. 439-459 (21 pages) An intricate repetitive fringe pattern, due to the ...

Researchers from the Institute for Materials Research at Tohoku University, in collaboration with the Japan Atomic Energy Agency and the RIKEN Center for Emergent Matter Science, have identified a new ...

THE peculiar character of the photographs of an opening to the sky in the dark Cyclopean gallery at Tiryns, to which Mr. W. J. Stillman calls attention (NATURE, vol. xxiv. p. 260), finds an obvious ...

Optics is a branch of physics that involves the properties of light and its interaction with matter. Reflection, refraction and diffraction are different ways light can behave based on the conditions ...

Scientists at the U.S. Department of Energy’s Ames Laboratory have discovered an indicator that reliably demonstrates a sample’s high quality, and it was one that was hiding in plain sight for decades ...

Producing structurally perfect graphene and other 2D materials is the secret to tapping into their potential novel electronic and spintronic properties. But how do we know when graphene, the most ...

It’s amazing what one can see in the great outdoors. I recently received an email from David Rudeen of Montague, California, who noticed a curious shadow effect. He said it starts with “strong, ...

(Nanowerk News) A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication technologies using acoustic devices. The research was led by ...
