The integral Squation of a "flat-roof resonator" is solved by the Fox and Li method of iteration in a number of particular cases.
Mode patterns, phase shifts, and power losses are derived. A good overall agreement is found with the approximate theory previously developed by Toraldo di Francia.
Some experimental tests carried out on a microwave model give a further confirmation of the theoretical predictions.
