Why Perfect Absorbers Do Not Exist: A Tutorial on the Derivation of the Rozanov Limit
In this tutorial, we explore one of the key theoretical frameworks that addresses the limits of electromagnetic absorption: the Rozanov bound. This mathematical constraint gives us insights into how efficient an electromagnetic absorber can be, answering the critical question: Is there an upper limit to the amount of energy a material can absorb? Through rigorous derivation and explanations, this tutorial aims to provide a comprehensive understanding of the Rozanov bound, shedding light on its significance in the design of highly efficient absorbers for various applications.
