Widening, Transition and Coalescence of Local Resonance Band Gaps in Multi-resonator Acoustic Metamaterials: From Unit Cells to Finite Chains
A. Stein, M. Nouh, T. Singh
Local resonance band gaps in acoustic metamaterials are widely known for their strong attenuation yet narrow frequency span. The latter limits the practical ability to implement su…
Multiple energy-scales in vertex-frustrated mesospin systems
Henry Stopfel, Unnar B. Arnalds, Aaron Stein +3
The interplay between topology and energy-hierarchy plays a vital role in the collective magnetic order in artificial ferroic systems. Here we investigate, experimentally, the effe…
Collective magnetic dynamics in artificial spin ice probed by AC susceptibility
Merlin Pohlit, Giuseppe Muscas, Ioan-Augustin Chioar +8
We report on the study of the thermal dynamics of square artificial spin ice, probed by means of temperature and frequency dependent AC susceptibility. Pronounced influence of the…
Dielectric Metasurfaces for Complete and Independent Control of Optical Amplitude and Phase
Adam C. Overvig, Sajan Shrestha, Stephanie C. Malek +4
Metasurfaces are optically thin metamaterials that promise complete control of the wavefront of light but are primarily used to control only the phase of light. Here, we present an…
Observation of the nonlinear Wood's anomaly on periodic arrays of nickel nanodimers
Ngoc-Minh Tran, Ioan-Augustin Chioar, Aaron Stein +6
Linear and nonlinear magneto-photonic properties of periodic arrays of nickel nanodimers are governed by the interplay of the (local) optical response of individual nanoparticles a…
Magnetic order and energy-scale hierarchy in artificial spin ice
Henry Stopfel, Erik Östman, Ioan-Augustin Chioar +6
In order to explain and predict the properties of many physical systems, it is essential to understand the interplay of different energy-scales. Here we present investigations of t…
