Abstract

Abstract

En 中文
• Analytical framework for multi-field coupling dynamics in non-Hermitian plates. • Programmable unidirectional circuits induce skin effect in 2D elastic continua. • Non-Hermitian skin effects break spatial symmetry, reshaping sound patterns. • Experimental demonstration of broadband vibroacoustic control via skin effect.
