Clear All Filters x radio frequency x
radio frequency

The frequency range for radio and television transmission.

radio-frequency discharge laser

A gas laser in which the electrodes are mounted perpendicular to the optical resonator.

radio-frequency light source

A very uncommon lamp in which a tungsten electrode is heated to incandescence by a radio-frequency electrical current.

radio-frequency linear accelerator

A device used to accelerate the electrons in a free-electron laser by channeling microwave energy into waveguide cavity assemblies.

attenuation

Attenuation refers to the gradual loss or reduction of intensity, force, or magnitude of a particular property as it propagates through a medium or travels over a distance. This concept is prevalent...

continuous wave

Continuous wave (CW) refers to a type of signal or transmission where the signal is constant and does not vary with time. In various contexts, the term is used to describe continuous, uninterrupted...

end-fire coupling

End-fire coupling refers to a method of coupling energy into or out of a waveguide, transmission line, or antenna, where the electromagnetic waves are directed primarily along the axis or direction...

HIRF

high-intensity radio frequency

light fidelity

LiFi, short for light fidelity, is a wireless communication technology that utilizes visible light or infrared light to transmit data. Developed as an alternative or complementary technology to...

linac -> linear accelerator

A device used to accelerate the electrons in a free-electron laser. There are several types, including the induction linear accelerator, the radio frequency linear accelerator and the superconducting...

optical cavity -> resonator

A resonator is a device or system that exhibits resonance, which is a phenomenon that occurs when an external force or stimulus is applied at a specific frequency, causing the system to oscillate...

optical resonator -> resonator

A resonator is a device or system that exhibits resonance, which is a phenomenon that occurs when an external force or stimulus is applied at a specific frequency, causing the system to oscillate...

radio astronomy

The detection and analysis of naturally formed extraterrestrial electromagnetic radiation within the radio frequency range of the spectrum.

radio telescope

An instrument designed to collect naturally formed extraterrestrial electromagnetic radiation within the radio frequency range of the spectrum in amounts sufficient to be measured.

resonant cavity -> resonator

A resonator is a device or system that exhibits resonance, which is a phenomenon that occurs when an external force or stimulus is applied at a specific frequency, causing the system to oscillate...
