Abstract

One of the method of implementing stealth technology in water is amplifying the energy dissipation of the incident wave,by using the special material, so that the reflection wave does not occur. In general, since this method depends a lot on the performance of the special material there are some limitations to improve the performance of the stealth. This study designed a metasurface that can amplify energy dissipation through structural design. By changing the incidence wave to surface wave, we can implement energy entrapment, and there will be lots of energy dissipation following the time and loss factor. If we can improve the residence time of the wave on metasurface, and also improve the loss factor, this study can give lots of effects on enhancing the performance of the underwater stealth technology.
