Bounds on the Uniaxial Effective Complex Permittivity of Two-phase Composites and Optimal or Near Optimal Microstructures
Kshiteej J. Deshmukh, Graeme W. Milton
Electromagnetic materials with a uniaxial effective permittivity tensor, characterized by its transverse () and axial () components, play a central role in th…
Mixed Finite Element Analysis of Flexoelectric Response: Exploring Unit Cell Stacking and Strain Gradient Modulation
Arash Kazemi, Kshiteej J Deshmukh, Susan Trolier-McKinstry +1
Flexoelectricity, a coupling between strain gradients and electric polarization, has attracted significant interest due to its critical role in enhanced effects at small scales and…
Wave-Freezing and other Phenomena in Temporal Metasurfaces driven by Nonlocal Interactions
Kshiteej J. Deshmukh
Space-time metamaterials, or materials with properties changing in space and time, have gained a wide-spread interest due to their exotic properties. In this Letter, we propose a n…
Bounds on the Quality-factor of Two-phase Quasi-static Metamaterial Resonators and Optimal Microstructure Designs
Kshiteej J. Deshmukh, Graeme W. Milton
Material resonances are fundamentally important in the field of nano-photonics and optics. So it is of great interest to know what are the limits to which they can be tuned. The ba…
Non-Local Phononic Crystals for Dispersion Customization and Undulation-point Dynamics
Arash Kazemi, Kshiteej J. Deshmukh, Fei Chen +4
Dispersion relations govern wave behaviors, and tailoring them is a grand challenge in wave manipulation. We demonstrate inverse design of phononic dispersion using non-local inter…
Multiband homogenization of metamaterials in real-space: Higher-order nonlocal models and scattering at external surfaces
Kshiteej Deshmukh, Timothy Breitzman, Kaushik Dayal
This work develops a dynamic homogenization approach for metamaterials. It finds an approximate macroscopic homogenized equation with constant coefficients posed in space and time;…
An Energy Conserving Mechanism for Temporal Metasurfaces
Kshiteej J. Deshmukh, Graeme W. Milton
Changing the microstructure properties of a space-time metamaterial while a wave is propagating through it, in general requires addition or removal of energy, which can be of expon…
