Topic: Electromagnetics
In the near field, the radiated waves take the form of
- A. Spherical wave
- B. Plane wave
- C. Cylindrical wave
- D. Conical wave
Answer: A. Spherical wave
Explanation: In the near field of a radiating source, the radiated waves take the form of spherical waves. These evolve into cylindrical waves in the intermediate region and finally appear as plane waves in the far field.
