Non-scattering multi-mirror systems for field localization

Research output: Chapter in Book/Report/Conference proceedingConference contributionScientificpeer-review


Resonators composed of two mirrors, such as Fabry-Perot cavities, provide a simple but effective approach to achieve wave transmission with high finesse. Further increase of the quality factor requires reflectors with higher conductivity or multi-mirror solutions. However, the analytical complexity of resonators with more than two mirrors prevents the design of optimal structures without recurring to numerical methods. This work considers an alternative approach to this problem by using cavities which do not produce any electromagnetic scattering. We demonstrate that these invisible cavities can be placed inside one another, resulting in a 'matryoshka-doll'-like resonator. The standing-wave distribution of the inner resonator can be controlled without disturbing that of the outer one, whereas the whole system remains non-scattering.
