WASHINGTON - Researchers have reported an approach to photoacoustic imaging that offers vastly improved resolution, setting the stage for detailed in vivo imaging of deep tissue. The technique is ...

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 ...

Regular readers will know that I love me some sub-diffraction-limited imaging. But even though I hate to admit it, light is not the only thing we use for imaging. You might imagine that I am thinking ...

A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication technologies using acoustic devices. The research, published in Physical ...
