The influence of skin effect on coaxial cable

The influence of skin effect on coaxial cable

2024-04-19

Coaxial cable is a type of electrical wire and signal transmission line, usually made up of four layers of material: the innermost layer is a conductive copper wire, and the outer layer of the wire is surrounded by a layer of plastic (used as an insulator or dielectric). There is also a thin mesh of conductive material (usually copper or alloy) outside the insulator, and the outer layer of the conductive material is used as the outer skin,as shown in Figure 1,Figure 2 shows the cross-section of a coaxial cable.
