Optical antennas, analogues of microwave and radiowave antennas, are a new concept in physical optics 1. They are an enabling technology for manipulating and controlling optical radiation at ...

Researchers have developed arrays of tiny nano-antennas that can enable sensing of molecules that resonate in the infrared spectrum. The semiconductor antenna arrays allow long-wavelength light to ...

This is equivalent to an array of 64 × 64 antenna units, or pixels, with each pixel covering 9 × 9µm. The antennas are made from a strong, high-index contrast dielectric grating and all work at the ...

The figure shows how much light (PLE, photoluminescence excitation) the individual pyramid-shaped antenna emits at various wavelengths (colours) of light in comparison to the antennas in the array.

The researchers fabricated a 64×64 "pixel" array of identical square antennas, each 9 microns (0.009mm) on the side. The entire array was formed out of silicon, with connecting silicon "wires ...

Would it be possible to design a phased array using individual antenna elements that combined the antenna design used here with the electronics in this other excellent post, all integrated on one ...

In recent years, Sengupta’s lab has designed antenna arrays that help engineers make strides toward peering through matter, boosting communications in canyons of skyscrapers, putting a medical lab on ...

Starlink's Phased Array Antenna Technology: The Key to Seamless Satellite Connectivity. In the realm of modern satellite communication, SpaceX's Starlink system stands out for its innovative use ...

Antenna-on-a-chip rips the light fantastic Date: November 16, 2012 ... "You have an array of pixels and you can change the transmission of each pixel at a very high speed," he said.

Ground has finally been broken today at two sites in Africa and Australia that will host the Square Kilometer Array Observatory (SKAO), the largest radio telescope in the world.

The array of aligned, but randomly placed, carbon nanotubes (Image: Wang, et al, Applied Physics Letters) The tubes were about 50 nanometers wide, hundreds of nanometers long and aligned randomly.

On December 16th, Amazon unveiled the design of the user antennas customers will use to receive internet from the company’s massive future satellite constellation, Project Kuiper.
