Light-controlled molecular motors can be used to create functional materials to provide autonomous motion, or in systems that can respond on command. For biological applications, this requires the ...

Crystals have always been admired for their optical brilliance, but only a few specialists know that crystals can reflect 100% of infrared light like a metal. The origin of this reflection is that the ...

In a new publication from Opto-Electronic Advances, the research groups of Professor Zhong-Qun Tian from Xiamen University, Xiamen, China and Professor Huigao Duan from Hunan University Changsha, ...

A new technique uses 'molecular antennas' to funnel electrical energy into insulating nanoparticles, creating a new class of ultra-pure near-infrared LEDs for medical diagnostics, optical ...

A novel, polarization-independent, wide-angle reception Chand-Bali nano-antenna is proposed. An adjoint-based optimization algorithm is used to create the same resonance at both linear polarizations ...

Stanford University researchers have demonstrated the potential of single SiC whiskers to function as narrowband infrared emitters that have controllable emission characteristics. An important goal is ...

The Model ATR26M6G-1 is a 26-MHz to 6-GHz, 5,000-W wideband, high-gain radiant arrow/log periodic antenna with the proprietary bent-element design. The 2.18-meter overall width antenna features a ...

Uniform gaps below ten nanometers boost tuning range and efficiency in graphene metasurfaces for mid-infrared sensing, imaging, and communications. (Nanowerk Spotlight) Picture a wafer-thin optical ...

Scientists at the Max-Planck-Institut für Biochemie in Martinsried near München, Germany, have used their infrared near-field microscope to study crystal lattice vibrations (Nature 418, 159, 11. July ...
