Optically assisted trapping with high-permittivity dielectric rings: Towards optical aerosol filtration
Rasoul Alaee, Muamer Kadic, Carsten Rockstuhl +1
Controlling the transport, trapping, and filtering of nanoparticles is important for many applications. By virtue of their weak response to gravity and their thermal motion, variou…
Experimental observations of topologically guided water waves within non-hexagonal structures
Mehul P. Makwana, Nicolas Laforge, Richard V. Craster +4
We investigate symmetry-protected topological water waves within a strategically engineered square lattice system. Thus far, symmetry-protected topological modes in hexagonal syste…
On three-dimensional dilational elastic metamaterials
Tiemo Bückmann, Robert Schittny, Michael Thiel +3
Dilational materials are stable three-dimensional isotropic auxetics with an ultimate Poisson's ratio of -1. We design, evaluate, fabricate, and characterize crystalline metamateri…
Micro-Structured Two-Component 3D Metamaterials with Negative Thermal-Expansion Coefficient from Positive Constituents
Jingyuan Qu, Muamer Kadic, Andreas Naber +1
Controlling the thermal expansion of materials is of great technological importance. Uncontrolled thermal expansion can lead to failure or irreversible destruction of structures an…
Clay metaBrick-based motif to enhance thermal and acoustic insulation
Brahim Lemkalli, Saad Bensallam, Muamer Kadic +4
Acoustic metamaterials have gained popularity as promising materials for enhancing noise reduction. Here, we explore the use of metamaterials, based on Helmholtz resonators (HRs),…
Theory of the Hall effect in three-dimensional metamaterials
Christian Kern, Graeme W Milton, Muamer Kadic +1
We apply homogenization theory to calculate the effective electric conductivity and Hall coefficient tensor of passive three-dimensionally periodic metamaterials subject to a weak…
