WebMirror symmetry of a wave system imposes corresponding even or odd parity on its eigenmodes. For a discrete system, eigenmode parity on a specific subset of sites may … Web1 de fev. de 2024 · Hidden symmetries analysis. Successive reduction processes of BKK equation are executed to transform it into another PDE system with only two independent variables. Then, the new PDE system is transformed into ODE. The main objective is to detect hidden symmetries that are not being inherited of the previous step. Exact …

Web8 de nov. de 2024 · Negative refraction plays an important role in acoustic wave manipulation and imaging. However, conventional systems based on acoustic metamaterials suffer from the limits induced by loss-related and resolution issues. In this work, a parity-time (PT)-symmetric system is introduced to realize loss-free bidirectional … Web14 de mar. de 2024 · Water waves, a common natural phenomenon, have been influential in various fields, such as energy development, offshore engineering, mechanical engineering, and hydraulic engineering.
