Cecil, 
 
Nice try. 
 
You first. 
 
Describe how you set up this coherent wave/anti-wave pair that happily 
travel together for some indeterminate distance. Then I will describe 
what happens when at some arbitrary point and time they decide to 
annihilate. 
 
I will repeat one more time, since you did not seem to understand 
previously. 
 
* Maxwell's equations are all that is needed. 
 
* Interference is *derived* from the correct application of Maxwell's 
equations. It is not an independent physical entity. 
 
* Interference may be "intuitive" and it may help your understanding, 
but it adds precisely nothing to the physics of the problem. Everything 
you believe is buried in the magic of interference is already built into 
Maxwell's equations.

 But there is, Gene. It's the only way to correct the present 
 misinformation and old wives' tales being promoted on this 
 newsgroup. It is obvious that the r.r.a.a poster who 
 understands the role that interference plays in the 
 conservation of RF energy is very rare. 
 
 There is a conspiracy to keep this information from 
 surfacing - "Nothing new", "no need", "irrelevant", 
 "who cares?" Why are you guys afraid to discuss the 
 technical details? 
 
 This should be an easy question to answer. If two coherent 
 waves of 50 joules/sec each, are traveling in the same 
 path in the same direction and are 180 degrees out of 
 phase, they cancel in that direction of travel. What 
 happens to their 50+50 joules/sec? Hint: energy doesn't 
 cancel and there are only two possible directions. Can 
 you spell R-E-F-L-E-C-T-I-O-N?
