Evaluation of Dynamics of Non-Scattering States in Nanophotonics

The Thesis focuses on studying new optical effects in the challenging subfield of ultrafast subwavelength optics. However, the specific subfield, namely transient optics of the non-scattering regimes, has not been developed yet and represents a vast field of activity. The Thesis is aimed at fundamental research in a new area and implementing fundamental models of new devices based on the results obtained. Within the Thesis framework, models have been developed, and prototypes of new ultra-thin planar photonic elements, such as ultra-thin repetition rate multipliers, light filters, beam modulators, etc., have been implemented. These elements are designed for femtosecond optics and have dual-use applications for both short pulses and continuous irradiation.
