Abstract :
There is a fundamental limit on the absorption-bandwidth integral that can be achieved by the use of frequency-dependent materials on a conducting backplane, proportional to the thickness of the structure, and to its magnetic permeability. The limit arises because the materials must be causal and passive. The value of the limit has been obtained by analytic calculation and verified by numerical experiment.
