A new method based on the thermal quadrupoles technique for heat transfer modelling in multilayered slabs with heat sources is proposed. Classical thermal quadrupoles use hyperbolic functions and numerical problems occur according to the argument value that depends on thermophysical and geometrical properties as well as characteristics times. We propose a new formulation based on exponential fu...
Metal-dielectric multilayered metamaterials are proposed to work as wideband spectral-selective emitters/absorbers due to the topological change in isofrequency contour around the epsilon-near-zero point. By setting the transition at the border between the visible and IR ranges, the metal-dielectric multilayered metamaterials become good absorbers/emitters for visible light and good reflectors ...
We analyze the evolution of the modes in nanoplasmonic multilayered structures and study the transition of the optical properties of these systems to the effective-medium regime. We derive the effective-medium parameters and study the validity of our analytical results with exact numerical solutions of Maxwell equations. Finally, we explore the applications of multilayered systems for subwavele...
A novel formulation for the linear buckling analysis of multilayered shells is presented. High-order equivalent-single-layer shell theories based on through-the-thickness expansion covariant components displacement field are employed. The novelty regards governing equations solution via implicit-mesh discontinuous Galerkin method. It a high-order accurate numerical technique representation amon...
A novel pure penalty discontinuous Galerkin method is proposed for the geometrically nonlinear analysis of multilayered composite plates and shells, modelled via high-order refined theories. The approach allows to build different two-dimensional equivalent single layer structural models, which are obtained by expressing covariant components displacement field through-the-thickness Taylor’s poly...
Guided bone regeneration is a new concept of large bone defect therapy, which employs a barrier membrane to afford a protected room for osteogenesis and prevent the invasion of fibroblasts. In this study, we developed a novel barrier membrane made from lyophilized multilayered acellular human amnion membranes (AHAM). After decellularization, the AHAM preserved the structural and biomechanical i...
