Temporal Effective Medium for Programmable Acoustic Metamaterials with Multiple Resonances
Xinghong Zhu, Hong-Wei Wu, Jensen Li
We extend effective medium theory (EMT) to time-modulated, frequency-dispersive acoustic metamaterials with multiple resonances. While previous studies focused on non-dispersive or…
