Abstract: Systems and methods using passive reflectors or reflectarrays are provided to enhance non-line-of-sight (NLOS) wireless signals. Multiple reflectarrays are combined and positioned to cover a wide range of user positions/beam angles. The passive reflectarrays include at least one of a first reflectarray configured to split an incident beam and a second reflectarray configured to steer the incident beam with an off-plane of incidence.

Abstract: A magnetic film includes a plurality of magnetically permeable particles dispersed between opposing first and second major surfaces of the magnetic film. The first and second major surfaces are spaced apart a distance D. The particles are agglomerated so as to form a plurality of substantially continuous layers of particles generally extending along orthogonal first and second directions and arranged along a third direction. Each substantially continuous layer of particles has a length L along the first direction from a first to an opposing second edge of the magnetic film and a width W along the second direction extending from the first to the second major surface. L/D ≥ 100.

Abstract: A magnetic isolator includes a dielectric film having a layer of electrically-conductive soft magnetic material bonded thereto. The layer of electrically-conductive soft magnetic material comprises substantially coplanar electrically-conductive soft magnetic islands separated one from another by a network of interconnected gaps. The interconnected gaps are at least partially filled with a thermoset dielectric material. The network of interconnected gaps at least partially suppresses electrical eddy current induced within the layer of soft magnetic material when in the presence of applied external magnetic field. An electronic device including the magnetic isolator and a method of making the magnetic isolator are also disclosed.

Abstract: A composite comprising a polymeric matrix and EM absorbers dispersed within the polymeric matrix. Each EM absorber comprises a dielectric flake, and a continuous magnetic coating on at least one major surface of the dielectric flake. The EM absorbers function as dielectric and magnetic absorbers in the 1-100 GHz frequency range. The composite can be used as an electromagnetic shielding article to mitigate electromagnetic interference in, for example, high speed, high frequency (HSHF) consumer electronics.

Abstract: Articles to control an electromagnetic (EM) radiation in the range of 1 GHz to 100 GHz, and methods of making and using the same are provided. An EM controlling sheet structure includes a dielectric carrier layer and an array of metallic resonant elements supported by the dielectric carrier layer to form an EM metamaterial structure in a non-random pattern. The metallic resonant elements are oriented such that each metallic resonant element has an axis substantially parallel to each other and substantially parallel to a major plane of the dielectric carrier layer.

Abstract: High frequency power inductor materials are provided to include a polymeric binder and a plurality of multilayered flakes dispersed in the polymeric binder. The multilayered flakes are dispersed in the polymeric binder and include at least two layer pairs. Each layer pair includes a layer of ferromagnetic material and a dielectric electrical isolation layer so that the ferromagnetic layers are electrically isolated from each other by dielectric layers. The multilayered flakes have an average lateral size less than 400 micrometers, less than 300 micrometers, or less than 200 micrometers. In some cases, the multilayered flakes are surface-treated with a phosphoric acid solution.
