Parametric Instability in Discrete Models of Spatiotemporally Modulated Materials
Jiuda Wu, Behrooz Yousefzadeh
We investigate the phenomenon of parametric instability in discrete models of spatiotemporally modulated materials. These materials are celebrated in part because they exhibit nonr…

Nonreciprocal Phase Shifts in Spatiotemporally Modulated Systems
Jiuda Wu, Behrooz Yousefzadeh
Materials and devices subject to spatiotemporal modulation of their effective properties have a demonstrated ability to support nonreciprocal transmission of waves. Most notably, s…

Linear Nonreciprocal Dynamics of Coupled Modulated Systems
Jiuda Wu, Behrooz Yousefzadeh
Waveguides subject to spatiotemporal modulations are known to exhibit nonreciprocal vibration transmission, whereby interchanging the locations of the source and receiver change th…
