Bandwidth of Linear Classically Damped Systems with Application to Experimental Model Aircraft
Benjamin J. Chang, Keegan J. Moore, Lawrence A. Bergman +2
Bandwidth is a widely known concept and tool used in structural dynamics to measure an oscillator's capacity to dissipate energy over time, for example when used in half-power damp…
Sub-Bragg Phenomena in Multilayered Vibroacoustic Phononic Metamaterials
Majdi O. Gzal, Lawrence A. Bergman, Kathryn H. Matlack +1
Beyond classical Bragg diffraction, we report on new sub-Bragg phenomena to achieve enhanced sound wave tunability in the low-frequency range in a multilayered acoustic metamateria…
Analytical Study of a Monolayered Vibroacoustic Metamaterial
Majdi O. Gzal, Lawrence A. Bergman, Kathryn H. Matlack +1
This study investigates a vibroacoustic phononic metamaterial system composed of repeated monolayered membrane-air cavity unit-cells to assess its efficacy in controlling sound wav…
Exceeding the Classical Time-bandwidth Product in Nonlinear Time-invariant Systems
Alireza Mojahed, Kosmas L. Tsakmakidis, Lawrence A. Bergman +1
The classical 'time-bandwidth' limit for linear time-invariant (LTI) devices asserts that it is impossible to store broadband waves (large Δω's) for long times (large Δt's). For st…
