This expression describes well peculiarities of non-stationary electromagnetic waves due to source-current filling: directionality, frequency transform and beating. Results obtained may be readily used in the case of scalar waves. ... Electromagnetic waves produced by a travelling current pulse with high-frequency filling...

Electromagnetic (EM) waves are produced by accelerating charges. They are changing electric and magnetic fields, carrying energy through space. EM waves require no medium, they can travel through empty space. Sinusoidal plane waves are one type of electromagnetic waves.

Perhaps the greatest theoretical achievement of physics in the 19th century was the discovery of electromagnetic waves. The first hint was an unexpected connection ... Faraday also showed that a magnetic field which varied in time--like the one produced by an alternating current (AC)--could drive electric currents,
