Superscattering and Directive Antennas via Mode Superposition in Subwavelength Core-Shell Meta-Atoms
Designing a subwavelength structure with multiple degenerate resonances at the same frequency can vastly enhance its interaction with electromagnetic radiation, as well as define its directivity. In this work we demonstrate that such mode superposition or ‘stacking’ can be readily achieved through t...
