Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz.This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies, and also encompasses the microwave range, though other definitions ...
When we think of electricity, we naturally think of wires. From high-voltage transmission lines to tiny traces on a printed circuit board, wires are still the fundamental means of transferring electrical energy from one location to another.
Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.. It is incorporated into almost everything that transmits or receives ...

May 23, 2022 · Profound RF is an FDA-cleared, minimally invasive skin rejuvenation procedure for the face and body. It uses a combination of microneedling with radiofrequency energy to firm skin, reduce the appearance of facial wrinkles, and fade scars. Ultra-thin needles deliver heat from the RF energy into the reticular dermis, the skin’s lower layer, to ...
