Mahmoud Hussein’s research focuses on the dynamics of materials and structures with particular attention on periodic materials at both the continuum and atomistic scales. Among his areas of interest are phononics and lattice dynamics of silicon-based nanostructured materials. His studies are concerned with physical phenomena governing these systems and relevant theoretical treatments. He has a special interest in the effects of dispersion, resonance, dissipation and nonlinearity. Recently he has also been conducting experiments to support the theoretical work. Among Prof. Hussein’s accomplishments is the development of the concept of a nanophononic metamaterial, which is a nanoscale metamaterial based on a pillared thin-film structure that allows the thermal conductivity to be reduced without affecting the electrical conductivity.
