Two orders of magnitude reduction in silicon membrane thermal conductivity by resonance hybridizations
Hossein Honarvar, Mahmoud I. Hussein
The thermal conductivity of a freestanding single-crystal silicon membrane may be reduced significantly by attaching nanoscale pillars on one or both surfaces. Atomic resonances of…
Thermal transport size effects in silicon membranes featuring nanopillars as local resonators
Hossein Honarvar, Lina Yang, Mahmoud I. Hussein
Silicon membranes patterned by nanometer-scale pillars standing on the surface provide a practical platform for thermal conductivity reduction by resonance hybridization. Using mol…
Generalized Bloch's theorem for viscous metamaterials: Dispersion and effective properties based on frequencies and wavenumbers that are simultaneously complex
Michael J. Frazier, Mahmoud I. Hussein
It is common for dispersion curves of damped periodic materials to be based on real frequencies versus complex wavenumbers or, conversely, real wavenumbers versus complex frequenci…
