Embodiment Construction
[0017] In this paper is described a concept for exploiting the unique properties of fabricated metamaterials (as absorbers) to produce radio frequency absorber (RFA) or fully microwave absorber (PMA) printed circuit boards (PCBs) by applying to layers in PCBs methods and devices. According to embodiments described herein, a metamaterial layer in a PCB can be used as an RFA or PMA layer.
[0018] Magnetic materials (eg, permalloy, musalloy, etc.) may be transformed into a physical format that will be suitable for use with an appropriate adhesive and for use in any of the embodiments described herein. Typically, magnetic materials can be processed from bulk metal to spheres, rods, or flakes. Magnetic material geometries used in absorbers It can be pointed out that flake geometries have clear advantages over other geometries when constructing successful absorbers. Additionally, the aspect ratio of the material in any geometry may be critical for achieving maximum permittivity a...
