The formula to calculate the Mean Flux Density of an Oscillating Electric Dipole is:

P_{avg} = (μ_{0} × ω^{4} × p^{2} × sin^{2}θ) / (12π × c^{3})

Where:

- P
_{avg}: Mean Flux Density - μ
_{0}: Permittivity of free space - ω: Angular frequency of oscillation
- p: Amplitude of the electric dipole moment
- sin
^{2}θ: The square of the sine of the angle between the direction of radiation and the dipole moment - c: Speed of light

This formula is a result of the classical theory of electromagnetic radiation, which was substantially developed by James Clerk Maxwell in the 19th century. While there is no single person credited with its derivation, it is based on the principles of electromagnetism established by Maxwell and has been refined by countless physicists and engineers over the years.

The calculation of the Mean Flux Density of an Oscillating Electric Dipole is extensively used in wireless communication systems. For example, in designing antennas for radio or television broadcasting, engineers need to understand the dipole radiation pattern, which can be determined by the mean flux density.

James Clerk Maxwell is a key figure in the field of electromagnetism. His formulation of the classical theory of electromagnetic radiation brought together all previous observations, experiments, and equations of electricity and magnetism into a consistent theory. His set of equations, known as Maxwell's equations, first published between 1861 and 1862, form the foundation of classical electrodynamics, classical optics, and electric circuits, which are still widely used today.

- The principles of oscillating electric dipoles are widely used in various technologies that have revolutionized human communication, including radio, television, and Wi-Fi.
