Abstract
A structure having layers of controllable electrical properties is prepared by furnishing a sheet of a substrate material, patterning a pattern of recesses into a surface of the sheet of the substrate material, filling the pattern of recesses with a mixture of an active phase and a matrix, and laminating the sheet to a base structure. The filled recesses may be of any desired shape, depth, and orientation. The active phase is particles of a material such as an electrical conductor or semiconductor, or magnetic particles.

A method of preparing a structure, comprising the steps of:
- furnishing a substrate material;
- patterning a set of recesses into a surface of the substrate material;
- filling the set of recesses with a mixture of an active phase and a matrix, wherein the active phase comprises a material selected from the group consisting of electrically conductive particles, semiconductor particles, and magnetic particles, and mixtures thereof;
- and thereafter
- laminating the sheet to a base structure comprising a material selected from the group consisting of a foamed sheet and a sheet of composite material.
A method of preparing a structure, comprising the steps of:
- furnishing a first substrate material;
- patterning a first pattern of recesses into a surface of the first substrate material;
- filling the first pattern of recesses with a first mixture of a first active phase and a first curable matrix, wherein the first active phase comprises a material selected from the group consisting of electrically conductive first particles, semiconductor first particles, and magnetic first particles, and mixtures thereof;
- curing the first mixture;
- furnishing a second substrate material;
