Theoretical seminar | 23 June 2021

The talk gives a brief overview of the history and current developments within the topic of fundamental bounds to electromagnetic metrics. The mathematical formulation of the underlying problem, based on the field integral equations and duality, is to be sketched and accompanied by selected examples ranging from static fields and optimal magnetic traps over radiofrequencies and optimal antennas to optics and optimal lenses.
