  2. RF probe - Wikipedia

    en.wikipedia.org/wiki/RF_probe

    RF probes are especially relevant for switches and RF traces in printed circuit boards as well as terminations of RF components. In such systems, like many other RF circuits, there is a higher requirement of matching probe impedance with that of the DUT. Efficient matching avoids reflection which in turn leads to efficient power transfer.

  3. Radiofrequency ablation - Wikipedia

    en.wikipedia.org/wiki/Radiofrequency_ablation

    Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).

  4. Radio-frequency engineering - Wikipedia

    en.wikipedia.org/wiki/Radio-frequency_engineering

    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.

  8. Microwave cavity - Wikipedia

    en.wikipedia.org/wiki/Microwave_cavity

    A microwave cavity or radio frequency cavity (RF cavity) is a special type of resonator, consisting of a closed (or largely closed) metal structure that confines electromagnetic fields in the microwave or RF region of the spectrum. The structure is either hollow or filled with dielectric material. The microwaves bounce back and forth between ...
