A. Outer plastic sheath. B. Woven copper shield. C. Inner dielectric insulator. D. Copper core. Coax. Cable. Coaxial cable, or coax is a type of cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Coaxial cable differs from other shielded cable used for carrying lower-frequency signals, such as audio signals in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a radio frequency transmission line..

When a charged particle loses energy, a tiny disturbance or ripple in the surrounding electromagnetic field is created – an e-m wave. . The wave will be in the same plane as the plane of movement of the particle. If all the disturbances in a ray of light were occurring in the same plane, the light is said to be .
