Frequency-selective spin-wave propagation in magnonic waveguide with a local laser-heated region

We report on the spin-wave propagation along a magnonic waveguide with a local area of decreased magnetization, which is induced by heating produced with a focused laser spot. A phase-sensitive Brillouin light scattering technique is used to image how the spin wave propagates along the waveguide with a local heat landscape. Frequency-selective signal propagation along the waveguide is demonstrated. Micromagnetic simulations reveal intermodal interference variation in the region after the heated area. The proposed way to reconfigure the magnetization landscape can be used in magnonic devices with frequency-selective spin-wave transport

NUMERICAL AND EXPERIMENTAL RESEARCH ON AERODYNAMICS OF A HIGH-SPEED PASSENGER VEHICLE WITHIN THE HEXAFLY-INT PROJECT

Hypersonic passenger transport is intrinsically linked to long-haul intercontinental flights. Its development and deployment will demand an international approach. The internationally funded HEXAFLY-INT project is a first step into this direction. Key elements for civil high-speed transportation are jointly developed towards an experimental flight. The present paper describes the various numerical and experimental investigations carried out so far by the different international partners.status: publishe
