  It can be agreed that the linear superposition and energy conservation are
two independent physics laws in general. The former allows the energy to be
re-distributed over space and the latter restricts the energy in the total
amount. However, Levine shows the contradiction of the two laws mentioned above
by creating a cleaver model that demonstrates the energy "doubling"- and
"missing" phenomenon with the constrictive- and destructive interference at
every point of whole space, respectively. While, he presented a wrong
explanation by using one of the radiating sources to compare with an isolated
source by the compensation of the impedance, where the mistake is simply
analyzed in this paper. By setting up a spatial symmetric- and asymmetric-mode,
we work upon Poynting theorem from the sources to the waves with the
considerations of the superposition. The theoretical results reveal the
invalidity of the energy conservation. Moreover, the experiments performed in
the microwave anechoic chamber confirm the theoretical conclusion.
