The Chebyshev Polynomial Series Frequency Modulation Model for Waveform Design and Analysis
Stephen P. Blackstock, Amaro Tuninetti, Dieter Vanderelst +2
Polynomial phase signals (PPS) are a staple of waveform design and analysis in sonar, radar, and communications fields. They also find application in the modeling of bioacoustic em…

Green's Function Approach to Model Vibrations of Beams with Spatiotemporally Modulated Properties
Benjamin M. Goldsberry, Andrew N. Norris, Samuel P. Wallen +1
The forced time harmonic response of a spatiotemporally-modulated elastic beam of finite length with light damping is derived using a novel Green's function approach. Closed-form s…

Strongly Nonlinear Wave Propagation in Elasto-plastic Metamaterials: Low-order Dynamic Modeling
Samuel P. Wallen, Michael R. Haberman, Washington DeLima
Nonlinear elastic metamaterials are known to support a variety of dynamic phenomena that enhance our capacity to manipulate elastic waves. Since these properties stem from complex,…
