| Abstract Scope |
Metamaterials are artificial structures whose physical properties (optical, acoustic, thermal, mechanical, or magnetic) may be tailored unprecedently to obtain unnatural behaviours through the design and arrangement of their unit building blocks and their interaction. In particular, magnetic metamaterials, inspired by optics transformation, have demonstrated promising perspectives for cloaking, compressing, guiding, or transferring magnetic fields.
By combining advanced theory and modelling with state-of-the-art techniques for creating and analyzing magnetic devices, we have proven that custom-designed magnetic metasurfaces can efficiently concentrate magnetic fields and exhibit the special feature of isotropic amplification. Our research indicates that employing metasurfaces at the microscale could open up new possibilities for enhancing the performance of magnetic field detectors and improving the effectiveness of small-scale energy harvesting materials. This can help generate sufficient energy to power low-power electronic devices, thus leading to the development of new approaches in energy-efficient information and communication technologies. |
