A blueprint for truncation resonance placement in elastic diatomic lattices with unit cell asymmetry
Hasan B. Al Ba'ba'a, Hosam Yousef, Mostafa Nouh
Elastic periodic lattices act as mechanical filters of incident vibrations. By and large, they forbid wave propagation within bandgaps and resonate outside them. However, they ofte…
The role of frequency and impedance contrasts in bandgap closing and formation patterns of axially-vibrating phononic crystals
Hasan B. Al Ba'ba'a, Mostafa Nouh
Bandgaps, or frequency ranges of forbidden wave propagation, are a hallmark of Phononic Crystals (PnCs). Unlike their lattice counterparts, PnCs taking the form of continuous struc…
Theory of Truncation Resonances in Continuum Rod-based Phononic Crystals with Generally Asymmetric Unit Cells
Hasan B. Al Ba'ba'a, Carson L. Willey, Vincent W. Chen +2
Phononic crystals exhibit Bragg bandgaps, frequency regions within which wave propagation is forbidden. In solid continua, bandgaps are the outcome of destructive interferences res…
Existence of Corner Modes in Elastic Twisted Kagome Lattices
Hrishikesh Danawe, Heqiu Li, Hasan Al Ba'ba'a +1
This Letter investigates the emergence of corner modes in elastic twisted Kagome lattices at a critical twist angle, known as self-dual point. We show that a special type of corner…
Formation of Local Resonance Band Gaps in Finite Acoustic Metamaterials: A Closed-form Transfer Function Model
H. Al Ba'ba'a, M. Nouh, T. Singh
The objective of this paper is to use transfer functions to comprehend the formation of band gaps in locally resonant acoustic metamaterials. Identifying a recursive approach for a…
