This is the basis of radio technology. RF current does not penetrate deeply into electrical conductors but tends to flow along their surfaces; this is known as the skin effect. Meer weergeven 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. … Meer weergeven Communications Radio frequencies are used in communication devices such as transmitters Meer weergeven While RF usually refers to electrical oscillations, mechanical RF systems are not uncommon: see mechanical filter and RF MEMS. Meer weergeven Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower Meer weergeven The radio spectrum of frequencies is divided into bands with conventional names designated by the International Telecommunication Union (ITU): Frequency … Meer weergeven Test apparatus for radio frequencies can include standard instruments at the lower end of the range, but at higher frequencies, the test equipment becomes more specialized.
