A steerable high-power microwave beam array includes an optical sub-system comprising a laser and an optical time delay unit and a parallel set of RF time delay units. The optical system and/or the RF delay subsystem are utilized to precisely delay the pulses from the microwave antenna elements to provide steerable beam forming.

A body armor plate is configured to provide ballistics protection to a wearer of the plate. For example, the plate may be configured to protect the upper torso of the wearer from high-speed, ballistic projectiles like bullets, shrapnel, and/or other projectiles. In some implementations, the plate may include one or more electronic modules formed integrally therewith. Formation of the electronic modules integrally with the plate may enhance the functionality of the plate, may enhance the convenience (e.g., the form factor, the weight, the portability, etc.) of the electronics modules, robustness of the electronics modules, and/or other aspects of the electronics modules. The combination of the plate and the electronics modules may specifically provide various enhancements to, for example, military or law enforcement personnel that rely on the plate for ballistics protection.

A voltage tunable dielectric varactor includes a tunable ferroelectric layer and first and second non-tunable dielectric layers. First and second electrodes positioned adjacent to the tunable ferroelectric layer form a tunable capacitor. A third electrode is positioned adjacent to the first non-tunable dielectric layer such that the third and first electrodes and the first non-tunable dielectric layer form a first blocking capacitor. A fourth electrode is positioned adjacent to the second non-tunable dielectric layer such that the fourth and second electrodes and the second non-tunable dielectric layer form a second blocking capacitor. The first and second electrodes can be positioned on a surface of the tunable ferroelectric layer opposite the generally planar surface of the substrate, with the first and second electrodes being separated to form a gap. The first and second non-tunable dielectric layers can also be positioned on the generally planar surface of the substrate. The third electrode can be positioned on the surface of the first non-tunable dielectric layer opposite the generally planar surface of the substrate such that the third and first electrodes form a second gap. The fourth electrode can be positioned on the surface of the second non-tunable dielectric layer opposite the generally planar surface of the substrate such that the fourth and second electrodes form a third gap.

A method of producing multilayered conformal coatings of tunable, low electronic loss ceramic composites is carried out by mixing two-phase BSTO/MgO into a base solution of typical lab grade acetone to form a mixed solution, inserting two platinum sheets separated into the mixed solution, applying a constant direct current (DC) bias across the two platinum sheets acting as electrodes, and stirring to reduce sedimentation of particles using a magnetic stirrer. Deposition is also performed on insulating substrates by initially coating them with conducting films of Au, performing BSTO deposition, and subsequently sintering the dielectric film so that the underlying metal film evaporates.
