Περίληψη: In this lecture, the speaker will review mathematical and computational frameworks to elucidate physical mechanisms for manipulating waves in a robust way at scales beyond the diffraction limit using subwavelength structures.
Imaging, sensing and spectroscopic techniques based on the use of subwavelength resonators, approaches which are rapidly gaining in popularity, allow one to overcome the severely ill-posed character of image reconstruction in biomedical applications and to achieve super-resolution imaging and sensing.
The speaker will present the extraordinary properties of subwavelength resonators and construct a unified mathematical approach for modelling subwavelength confinement and guiding of waves as well as imaging and sensing using artificial materials. He will also evaluate the robustness of the proposed approaches with respect το uncertainties in the geometrical or physical parameters.
