There are not two walls to a room nor just two walls to surround a city. You are the one who is crying, mudding up the theory and trying to put others down rather than understand. There is nothing to gain by causing confrontation, so let's stop it.
In a rectangular waveguide resonance occurs in both between the long and between short sides of rectangular part of the waveguide. Dislocation loops allow for a greater range between upper and low cut off frequencies. The requirement for specific frequencies to cause clusters is valid theory for the success of dislocation loops as compared to crystal metal. The theory fits with Miley report. Further, Brilliant Light Power liquifies the metal which would cause same effect as dislocation loops only more of them. BLP gets even more energy with the same ingredients: metal, water and electricity.
As I suspected, you confused a microwave guide with a resonator. A microwave guide has four walls (to use your terminology) while a resonator (your microwave oven, for instance) has six. What I don't get is why you feel a need to complicate a simple theory? It seems that many of the participants here are so deeply involved in their theories that they can not see the simplicity and beauty of other approaches to problems.
