A wave propagation laboratory is proposed which enables the study of the interaction of broadband signals with complex materials. A physical experiment is dynamically linked to a numerical simulation in real time through transmitting and recording transducer surfaces surrounding the target. The numerical simulation represents an arbitrarily larger domain, allowing experiments to be performed in a total environment much greater than the laboratory experiment itself. Specific applications include the study of non-linear effects or wave propagation in media where the physics of wave propagation is not well understood such as the effect of fine scale heterogeneity on broadband propagating waves.
本文提出了一种波传播实验室，该实验室能够研究宽带信号与复杂材料之间的相互作用。通过围绕目标的发射和记录换能器表面，物理实验与数值模拟实时动态连接。数值模拟代表了一个任意大的区域，使得实验能够在比实验室实验本身大得多的整体环境中进行。具体应用包括研究非线性效应或波在传播物理尚未完全理解的介质中的传播，如细尺度非均匀性对宽带传播波的影响。
