Total Radiated Power of Oscillating Dipole Calculator

The total radiated power of an oscillating dipole, an important concept in Electromagnetism and Antenna Theory, pertains to the total energy emitted per unit time by the dipole as it oscillates. Factors such as the oscillation frequency, amplitude of the dipole moment, permittivity of free space, and speed of light play significant roles in these calculations.

Example Formula

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

Where:

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

The total radiated power of an oscillating dipole is crucial in antenna design for wireless communication systems, including radio, television, and mobile networks. The power radiated by an antenna, which acts as an oscillating dipole, determines its efficiency and the quality of signal transmission and reception.
