Example Formula

The formula to calculate the total radiated power of an oscillating dipole is:

P = (μ0 c I2 ω4 a2) / 12π


  1. P is the total radiated power.
  2. μ0 is the permittivity of free space.
  3. c is the speed of light.
  4. I is the amplitude of the dipole moment.
  5. ω is the angular frequency of oscillation.
  6. a is the maximum displacement during oscillation.

Who wrote/refined the formula

The formula was developed through the works of many scientists over the years, but the final form and its implications were detailed by James Clerk Maxwell as part of his seminal work on Electromagnetic Theory.

Real Life Application
