Feb. 28, 2022 Researchers report that lab tests of a new metasurface-based antenna that can harvest 100 microwatts of power, enough to power simple devices, from low power radio waves. This represents an important ...
July 9, 2021 Researchers have achieved micrometer spatial resolution for radio-frequency imaging of nitrogen-vacancy centers in diamond by enhancing the signal with quantum spin-locking. This work may lead to ...
July 8, 2021 Researchers have used the latest wireless technology to develop a new radio receiver for astronomy. The receiver is capable of capturing radio waves at frequencies over a range several times wider ...
Mar. 25, 2021 From microwave ovens to Wi-Fi connections, the radio waves that permeate the environment are not just signals of energy consumed but are also sources of energy themselves. An international team of ...
Nov. 10, 2021 Engineers have successfully transferred digitally encoded information wirelessly using nuclear radiation instead of conventional technology. The researchers measured the spontaneous emission of fast ...
Jan. 11, 2022 Researchers have now succeeded in producing an extremely simple and compact source of terahertz radiation: An oscillator with double resonant-tunneling diodes. Its radiation power significantly ...
Aug. 2, 2023 New interference radar functions improve the distance resolution between objects using radar waves. The results may have important ramifications in military, construction, archaeology, mineralogy and ...
Nov. 9, 2022 Researchers have found a way to avoid the need to use radio transmitters in critical communications, using new technology featuring super-fast optical ...
Oct. 17, 2023 Physicists have used a small glass bulb containing an atomic vapor to demonstrate a new form of antenna for radio waves. The bulb was 'wired up' with laser beams and could therefore be ...
June 3, 2022 Researchers have revealed a new beam-steering antenna that increases the efficiency of data transmission, and opens up frequencies for mobile communications that are inaccessible to currently used ...
