Abstract: A method and apparatus for producing a radio frequency absorbing (RFA) or perfect microwave absorbing (PMA) printed circuit board (PCB) is described herein. A metamaterial layer may be applied to a low dielectric substrate. Resistive and capacitive components may then be added to the metamaterial layer. The metamaterial layer may then be formed into an RFA or PMA PCB, which may comprise a multi-layered assembly for absorption of electromagnetic radiation in a targeted frequency range such as the microwave frequency range in the PCB.

Abstract: A method for producing a magnetic resonant frequency (MRF) absorber and apparatus for an MRF absorber are described herein. The method comprises processing a high permeability material such as permalloy comprising 80% nickel, 18% iron, 2% molybdenum to create a specific geometric form factor such as a flake, sphere, or rod. The geometric form factor may then be encapsulated in an insulating matrix. The insulating matrix may be a Potassium Silicate (SiO3K2). The insulated flake, sphere, or rod form factor may be introduced to a powder coating process. The insulated flake, sphere, or rod form factor may then be mixed with a polymeric coating powder at a weight ratio based on a desired performance for absorbing electromagnetic interference (EMI).

Abstract: A method and apparatus for producing a radio frequency absorber (RFA) or perfect microwave absorber (PMA) skin is described herein. A metamaterial layer may be applied to a low dielectric substrate. Resistive and capacitive components may then be added to the metamaterial layer. The metamaterial layer may then be formed into an RFA or PMA skin, which may then be applied to a multi-layered assembly for absorption of electromagnetic radiation in a frequency range such as the microwave frequency spectrum in a final product including but limited to cell phones, communication devices, or other electronic devices.

Abstract: A package is provided for use with a track-and-trace data management system. The package comprises a base defining a plurality of compartments, each compartment containing an item, and a cover enclosing the compartments to retain each item inside a respective compartment. Each item carries a unique item code, and the package includes at least one unique security code. The relationship between the unique item code and the at least one unique security code is maintained by the data management system.

Abstract: A secure identification card is created. The secure identification card includes a first identifying item of information. A first covert marker is applied to the secure identification card. The first covert marker is associated with the first identifying item of information such that the secure identification card is recognized as authentic only if the association between the first covert marker and the first identifying item of information is recognized. The association between the first covert marker and the first identifying item of information is stored at a site that can be used to monitor the use of the secure identification card at a plurality of locations.
