Extremely low frequency wave localization via elastic foundation induced metamaterial with a spiral cavity
Abstract We proposed a metamaterial which exhibits elastic wave localization at extremely low frequencies. First, we opened an extremely low bandgap via elastic foundations. Subsequently, we investigated wave localization by imposing normal defect, which is widely used to capture waves in convention...
