Radiofrequency waves in lossy media Inductive effects through a cylindrical body

courants de conduction; conductive currents

Currents generated by the propagation of a radio wave in an absorbent medium. In a metal, conduction currents are activated by the mobility of electrons, in an electrolyte by the mobility of ions.

transition pulsation; phase angle frequency transition

Concept referring here to the pulsation of a wave delimiting the propagation domain where conduction currents cease to dominate over displacement currents.

surface impedance; impédance de surface

For a cylindrical body, a quantity calculated by forming the ratio of the electric field appearing on the lateral surface of the object to the current penetrating its circular section. Strictly speaking, the definition of surface impedance refers, in the context of the cylinder, to...
