Mechanism of Band Gap Formation in Beam Networks
Kwangmin Lee, Charles Emmett Maher, Katherine A. Newhall +1
Band gaps are commonly attributed to Bragg scattering or local resonance, yet it remains unclear whether these mechanisms govern band gap formation in beam networks. In this work,…
Effect of Local Topological Changes on Resistance in Spatially-Embedded Disordered Networks
Chenxi Wang, Charles Emmett Maher, Katherine A. Newhall
Disordered materials occur naturally and also provide a broader design space than ordered or crystalline structures. We investigate a two-dimensional disordered network metamateria…
Probing the influence of topological and geometric disorder on the spectrum of the differential Laplacian operator on networks
Charles Emmett Maher, Jeremy L. Marzuola, Katherine A. Newhall
Metric networks are network-shaped, one-dimensional structures on which one can solve differential equations to simulate a wide range of physical systems including conjugated molec…
Local Geometric and Transport Properties of Networks that are Generated from Hyperuniform Point Patterns
James V. Raj, Xiaohan Sun, Charles Emmett Maher +2
Hyperuniformity, which is a type of long-range order that is characterized by the suppression of long-range density fluctuations in comparison to the fluctuations in standard disor…
Comparing dragonfly wings to jars of marbles through the lens of hyperuniformity
Karen E. Daniels, Charles Emmett Maher, Katherine A. Newhall +2
When we look at the world around us, we see both organized (also called ordered) and disorganized (also called disordered) arrangements of things. Carefully-tiled floors and brick…
