A practical method to reveal how an unknown interference source radiates energy.
It shows you how to measure and interpret radiation characteristics with a simple test setup.
This guide explains a method for determining the radiation characteristics and total power of an unknown interference source. Using a transverse electromagnetic (TEM) cell, a precise measurement of how energy couples into the cell’s modes leads to a full picture of the source’s radiation pattern. The approach combines theory and measurement with careful handling of phase and power data to produce amplitudes and relative phases of the source’s dipole moments.
- Learn how to position the source at the center of a TEM cell and collect sum and difference powers and their relative phases.
- See how measurements at six positions, guided by a well‑developed theory, yield the radiation pattern and total radiated power.
- Explore practical examples, including a spherical dipole radiator, to illustrate the procedure.
- Understand how to compute dipole moments and cross terms to build the full free-space radiation picture.
Ideal for readers involved in RF testing, interference analysis, or radiation measurements who want a validated procedure for extracting a source’s emission characteristics from practical data.
