Question

Equivalence Principle follows which f the following theorem?

(a) Uniqueness Theorem

(b) Poynting theorem

(c) Friss Theorem

(d) Gauss theorem

This question was addressed to me in an international level competition.

My doubt stems from Uniform Aperture Field topic in portion Aperture Antenna of Antennas

Answer 1

Correct answer is (a) Uniqueness Theorem

The best explanation: Equivalence principle follows the uniqueness theorem. It provides a unique solution for the boundary conditions. Uniqueness theorem is defined from the pointing theorem. Friss transmission is used to relate the distance and power radiation between the antennas. Gauss theorem states that total electric flux enclosed by charge is equal to net positive charge.
