Abstract: In this letter, a novel X-band amplifying metasurface with power amplifiers is proposed to enhance the reflected electromagnetic (EM) signals. The amplifying metasurface is designed based on ...

It has long been considered common sense that a single device performs only one function. Just as tuning a radio to a different frequency changes the channel, systems that manipulate waves have ...

A new wave of research is showing what the old gym myths about stretching got wrong—and what you really need to do to reap its benefits. Some fitness experts recommend stretching before a workout, ...

Several gloved hands hold the corners of and twist a thin screen that is glowing green. Organic light-emitting diode (OLED) displays can now be designed into flexible, stretchable screens like the ...

Wolverhampton Wanderers stretchered their Premier League unbeaten streak to four matches with a scoreless draw against poor Newcastle United on Sunday. It was the first nil-nil league draw between ...

A new OLED design can stretch dramatically while staying bright, solving a problem that has long limited flexible displays. The breakthrough comes from pairing a highly efficient light-emitting ...

A flexible, stretchable display introduces futuristic automotive interface design. Trump orders release of Arkansas congressman's son serving drug sentence 'A Knight of the Seven Kingdoms' is an ...

MXene electrodes and stretchable polymers enable OLED displays that maintain light output under strain for on-skin sensors and wearable health monitoring. (Nanowerk News) The organic light-emitting ...

The organic light-emitting diode (OLED) technology behind flexible cell phones, curved monitors, and televisions could one day be used to make on-skin sensors that show changes in temperature, blood ...

Optical metasurfaces, with their ultra-thin and lightweight properties, are driving the miniaturization and planarization of optical systems. However, their development from unit-cell design to system ...

A new technical report titled “Polymer semiconductor blends with remarkably stable semiconducting performance under large and cyclic mechanical deformation” was published by Chinese Academy of ...
