EMSWIM · Electromagnetic and spin wave interactions in magnetic nanostructure-based metamaterials and devices

The proposal is focused on the fundamental and applied research of electromagnetic and spin wave processes in laterally patterned periodic nanostructures and derived metamaterials and devices, with particular interest in magnetic materials. The research aims at the development and computer implementation of a theoretical approach capable of modeling the electromagnetic response of the nanostructures, their numerical and experimental investigation, proposing and designing novel applications, and studying related physical phenomena such as photon-spin wave interactions. Graphical, user-friendly software based on the numerical algorithm will be utilized for a commercial scatterometric system in the frame of international collaboration with Dainippon Screen Mfg. Co. Ltd., Japan. The project will use magneto-optical spectroscopy available at the host institution and other optical, magneto-optical, and complementary magnetism- and surface-science techniques provided by collaborating laboratories in the Czech Republic, Germany, and Japan. The results obtained on the nanostructures will be used to propose and design novel artificial metamaterials (such as magneto-photonic crystals) and devices (such as waveguides, microcavities, polarizing, space-modulating and other optical filters).
