Abstract
A meta material anisotropic, thermal insulation shield, designed to significantly improve performance of the thermal insulation by controlling path of heat flux passing through the system. Meta material techniques to enhance the thermal performance of insulating materials using thermal cloaking and/or heat flux rotation are disclosed. Meta material thermal insulating shield is implemented using anisotropic thermal insulation system comprising of rotated periodic layers of contrasting materials and thermal cloaks. Meta material insulation system can provide a system with thermal conductivity, which is much lower than the traditional systems. In other words, a meta material thermal insulation system having a much lower U-value than a traditional thermal insulation system can be designed.
Claims22
A meta-material drywall and/or insulation building panel with an anisotropic heat dissipating effect, comprising a first planar side, a second planar side parallel to said first planar side, a plurality of inner layers disposed between and parallel to said first planar side and said second planar side;
- said plurality of inner layers of said building panel alternates between an inner layer formed from a first material and an inner layer formed from a second material, each said inner layer of said plurality of inner layers formed, at least partially, as an offset curves with non-zero curvature of at least one other inner layer of said plurality of inner layers, and each of said first material and said second material are isotropic;
