Effects of geometry on static and band gap properties of 3D printed metastructures
… capabilities of a periodic and locally resonant metastructure design platform. We numerically study the influence of four different lattice topologies on the dynamic and static behavior of metastructures that combine a periodic lattice geometry with locally resonant inclusions. We analyze the …

Analytical and Spectro-Spatial Analyses of Nonlinear Metamaterials for Vibration Control, Energy Harvesting, and Acoustic Non-Reciprocity
… this thesis studies the passive self-tuning of a metastructure via a beam-sliding mass concept. The governing equations of motions of the holding structure, resonator, and sliding mass are presented and discretized into a system of ODEs using Galerkin's projection. Given that the spatial …

Implementation of Residual Tandem Neural Networks for Photonic Inverse Design
… the predictive model (the model that takes in a metastructure geometry and outputs a spectrum) acting as the ground truth. Region of Interest (ROI) modeling is also used to target particular regions in the optical spectrums that are of interest and produce highly targeted meta-surface geometries. …

Low-Frequency Emission Enhancement by Resonant Acoustic Metamaterials
… two in phase acoustic sources inside the metastructure with certain source configurations.

Study on Bandgap Manipulation and Structural Vibration Control in Sandwich Metastructures
… in acoustic and mechanical metamaterials, metastructures with wave manipulation capabilities have opened up new possibilities for structural vibration control. Compared with conventional vibration control approaches, metastructures can attenuate vibrations within specific frequency ranges …
