Reconfigurable intelligent surfaces (RIS) are engineered structures comprised of several elements known as 'meta-atoms,' ...

Electron holography is based on the fundamental principles of holography, which involves the recording and reconstruction of wavefronts. In holography, a hologram is created by capturing the ...

Akonia Holographics, a startup in Longmont, Colorado, spent years trying to make holographic data storage work. It didn’t succeed, but now it found a new use for the same technology. The company now ...

Creating three-dimensional shapes from basic elements or even cells is an important research topic, with potentially many applications in the fields of medicine and general research. Although physical ...

Sensing: point-of-care sensors, mobile-phone enabled sensors, field-based sensing and measurement systems with applications in mobile health and telemedicine, environmental monitoring (for example, ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.210009 overviews linear polarization holography. In conventional holography, the hologram is formed by recording the interference ...

The idea, put forth by Juan Maldacena of the Institute for Advanced Study in Princeton, N.J., suggested something profound: that our universe could be a hologram. Much like a 3D hologram emerges from ...
