    Abstract: An integrated heterostructure material is achieved by combining the attributes of two perovskite oxide film growth methods, RF sputtering and the metallo-organic solution deposition (MOSD) technique, in combination with employing a novel integrated material design consisting of a SrTO3 thin film layer which serves as a template to achieve a property enhanced, BST-based thin film overgrowth. In specific the integrated materials design consists of a thin RF sputtered SrTiO3 film (lower layer) which underlies a substantially thicker MOSD over-growth Mg doped BST-based film (upper layer). The inventive material design and combinational film growth fabrication method thereof enables beneficial critical material/device characteristics which include enhanced dielectric permittivity in concert with low loss; low leakage current density; high voltage breakdown strength; high tunability; controlled and optimized film microstructure; and a smooth surface morphology with minimal surface defects. The invention enables miniature highly (voltage) tunable frequency agile devices and/or charge mediated voltage controlled magnetic devices for RF/microwave communications, RADAR, and electronic warfare applications.

    Abstract: Embodiments of present inventions relate to low-profile, tapered cavity broadband antennas. One important aspect of the invention (although not the only) is the incorporation of a tapered lateral sidewalls in the antenna cavity. More particularly, according to various embodiments, a low-profile, tapered cavity antenna may comprise: an aperture defining an opening to a cavity; and an interior space defined by the cavity which is formed of a flat bottom wall defining a ground plane, and a pair of spaced-apart, tapered lateral sidewalls extending away from the flat bottom wall in opposite directions toward the aperture. The tapered shape of the tapered lateral sidewalls are specifically configured to maintain a constant resonance frequency within the cavity. In some embodiments, an isotropic high index medium material is at least partially loaded within the tapered cavity. Also, antenna may include a single or two-input port.

    Abstract: Rate-dependent, elastically-deformable devices according to various embodiments can be stretched and recovered at low elongation rates. Yet they become stiff and resistive to stretching at high elongation rates. In one embodiment, a rate-dependent, elastically-deformable device includes an elastically-deformable confinement member; one or more filaments placed inside the elastically-deformable confinement member; and a fluid that substantially fills the remaining volume inside the elastically-deformable confinement member. The resistance force to extension of the device is designed to increase as the extension rate of the device increases. At low elongation rates the filaments can readily slide past each other. At high elongation rates, the fluid transforms to a less flowable material that greatly increases the force and energy required for elongation; or transforms to a non-flowable material that resists elongation. The devices thus can be stretched and recovered at low elongation rates, but become extremely stiff and resistive to stretching at high elongation rates.
