Here we report about the strain-tuned dipolar spin-wave coupling in the adjacent system of yttrium iron garnet stripes, which were strain-coupled with the patterned piezoelectric layer. Spatially-resolved laser ablation technique was used for structuring

Balancing the complexity and the simplicity has played an important role in the development of many fields in science and engineering. As Albert Einstein was once quoted to say: 'Everything must be made as simple as possible, but not one bit simpler'. The simplicity of an idea brings versatility of that idea into a broader domain, while its complexity ...

Supertoroidal light pulses as electromagnetic skyrmions propagating in free space
Topology in electromagnetic fields can lead to a range of intriguing and unexpected phenomena. Here the authors describe a family of supertoroidal light pulses that exhibit skyrmionic topological structure flying in free space.

Toy model of harmonic and sum frequency generation in 2D dielectric nanostructures
Optical nonlinearities of matter are often associated with the response of individual atoms. Here, using a toy oscillator model, we show that in the confined geometry of a two-dimensional dielectric nanoparticle a collective nonlinear response of the ...

Abstract Mechanical metamaterials, also known as architected materials, are rationally designed composites, aiming at elastic behaviors and effective mechanical properties beyond (‘meta’) those of their individual ingredients—qualitatively and/or quantitatively.

Electronically steered metasurface antenna
Mobile devices, climate science, and autonomous vehicles all require advanced microwave antennas for imaging, radar, and wireless communications. We propose a waveguide-fed metasurface antenna architecture that enables electronic beamsteering from a ...

Flexible metamaterials for advanced photonics applications [PDF]
We present our recent results on the design, fabrication and applications of flexible metamaterials in the visible and near infrared range. In particular, we demonstrate broad angle spectral filtering for lab-on-fibre applications, the realisation of ...

Plasmonics and metamaterials have attracted considerable attention over the past decade, owing to the revolutionary impacts that they bring to both the fundamental physics and practical applications in multiple disciplines. Although the two fields initially advanced along their individual trajectories in parallel, they started to interfere with each ...

Orbital angular momentum and polarization states of highly focused vector vortex beams can be engineered to selectively excite the desired multipoles in nanoparticles, making them ideal candidates for complex optical applications. A platform based on the
