RF and microwave discharge

An RF or microwave discharge is an electrodeless gas plasma sustained by an oscillating electromagnetic field through a dielectric wall, coil, or waveguide rather than metal electrodes.

RF cavity filter

An RF cavity filter is a high-Q radio-frequency filter built from resonant metal cavities, preferred from about 40 to 960 MHz and used in FM and TV broadcast plants.

RF energy harvesting

RF energy harvesting converts ambient radio-frequency energy from sources like Wi-Fi and broadcast towers into DC power for battery-free sensors, RFID tags, and other low-power electronics.

RF fingerprinting

RF fingerprinting, also called radio frequency fingerprint identification or specific emitter identification, is a physical-layer technique that identifies a wireless transmitter from hardware-intrinsic imperfections in its waveform, without shared credentials.

RF MEMS switch

An RF MEMS switch is a microelectromechanical device that routes radio-frequency signals by moving a microscopic conductive beam, offering relay-like linearity with low power use.

RFA One

RFA One is a three-stage small orbital launch vehicle developed by Rocket Factory Augsburg, a German company majority-owned by OHB, designed to carry small satellites to low Earth orbit.

Rfam

Rfam is a curated database of non-coding RNA families, each with a seed alignment, consensus secondary structure, and covariance model searched via Infernal. Founded 2002; release 15.1 (2026) holds 4,227 families; excludes piRNAs and lncRNAs.

RFC 1

RFC 1, titled Host Software, is the first document in the Request for Comments series, written by Steve Crocker of UCLA and issued in April 1969.

RFC Editor

The RFC Editor is the publication function that edits, publishes, and archives the Request for Comments (RFC) series, the Internet's technical document series running since 1969.

RFC1

RFC1 (replication factor C subunit 1, HGNC:9969) is a gene at 4p14 encoding the large RFC subunit for PCNA loading; biallelic intronic AAGGG repeat expansions cause CANVAS and late-onset ataxia.

RFT1-CDG

RFT1-CDG, once called CDG type In, is an extremely rare autosomal recessive glycosylation disorder caused by RFT1 gene variants, mainly affecting the nervous system with epilepsy and deafness.

RFU Championship

RFU Championship, rebranded Champ Rugby from 2025-26, is English rugby union's second tier below the Premiership: 14 clubs, RFU-administered, funding cut from £600,000 to £160,000, promotion play-off until 2026-27.

RFX

RFX (Reversed Field eXperiment) is the largest reversed-field pinch magnetic confinement fusion experiment, built in Padua, Italy, producing first plasma in 1991 and now operating as RFX-mod2 for both RFP and tokamak research.

RG-31 Nyala

The RG-31 Nyala is a South African 4x4 mine-protected armored personnel carrier developed in the mid-1990s from the Mamba design, with a V-shaped hull that deflects mine blasts.

RGB-D salient object detection

RGB-D salient object detection (RGB-D SOD) is a computer vision task that finds the most prominent objects in a scene using a color image plus a depth map.

RGB-D SLAM

RGB-D SLAM is a form of visual simultaneous localization and mapping in which an RGB-D camera supplies color and depth, removing the scale ambiguity of monocular systems.

Rh disease

Rh disease, or Rh hemolytic disease of the fetus and newborn (erythroblastosis fetalis), occurs when an RhD-negative mother's anti-D IgG crosses the placenta and destroys RhD-positive fetal red cells; anti-D prophylaxis since 1968 has cut incidence about 95%.
