Rectangular waveguides loaded with magnetised ferrite, and the so-called thermodynamic paradox

The so-called thermodynamic paradox associated with a ferrite-loaded rectangular waveguide is discussed. It is shown that the various structures introduced by some authors to resolve the paradox are, even in the limit case, different structures from the original one leading to the paradox, and therefore they do not help in the resolution of the apparent inconsistency. Some experiments have been carried out in order to explain how, in a physical structure, the power is actually dissipated.
