DOI: 10.1103/physrevlett.121.094301
Abstract: Although topological mechanical metamaterials have been extensively studied from a theoretical perspective, their experimental characterization has been lagging. To address this shortcoming, we present a systematic, laser-assisted experimental characterization of topological kagome lattices, aimed at… read more here.

DOI: 10.1109/jsen.2024.3511626
Abstract: Silicon nanopillars (SiNPs) have attracted considerable interest due to their improved optical characteristics in the near-infrared (NIR) range. However, their high selectivity restricts their practical applications. In this study, we investigate how asymmetric wave-shaped sidewall… read more here.

DOI: 10.1155/2023/5736419
Abstract: The irreducible representations of the extended Galilean group are used to derive the symmetric and asymmetric wave equations. It is shown that among these equations only a new asymmetric wave equation is fundamental. By being… read more here.
