which will perfectly reflect an incoming RF signal back to its source. Second, waves that travel in the same medium overlap each other and their peaks and troughs can be summed. If two waves peak ...

Utilizing a 1MHz RF wave, it effectively heats the dermis to stimulate collagen regenerationand revitalise the skin. Additionally, the integrated intelligent temperature control chip ensures safe ...

The researchers developed a system called MiFly, in which a drone uses radio frequency (RF) waves, reflected by a single tag placed in its environment, to autonomously self-localize. Because MiFly ...

Hack-A-Day friend [Limor] AKA [ladyada] has been promising a portable RF jammer for a while. guess what she sent me for Christmas? The Wave-bubble is a self tuning RF jammer – good for around 20 ...

It enables drones to self-localize through radio frequency (RF) waves. This innovation could change the way drones are used in warehouses, tunnels, and other indoor spaces. “As our understanding ...

One area of research pursued the realization of a microwave oscillator based on RF photonics. Oscillators are devices that produce periodic waves whose amplitude, phase and frequency can be ...

The research team's MiFly system uses a type of high frequency radio waves called millimeter waves (mmWave) bounced between a low-power 'tag' (technically a backscatter anchor) stuck on a wall in ...

Eddie Ball was awarded a Fellowship by the UKRI in “Future Millimetre Wave RF Transceiver Architectures for Communications Systems”. This transformational research award will investigate advanced ...
