Abstract: A novel methodology for automatically linearizing a harmonic radar transmitter—termed Feed-Forward Filter Reflection (FFFR)—is disclosed. The method combines the reflected second harmonic from a filter with the signal passing directly through the filter. The second harmonic from these two paths are combined with equal and opposite amplitudes to reduce the second harmonic beyond filtering alone. This methodology has been experimentally verified at transmit frequencies between 800 and 1000 MHz. Implemented properly, the technique provides greater than 100 dB rejection between 1.6 and 2.0 GHz. Although the tuning has been automated, further optimization is possible. Automated tuning is demonstrated over 400 MHz of bandwidth with a minimum cancellation of 110 dB. One application for the harmonic cancellation is to create a linear radar transmitter for the remote detection of non-linear targets.

Abstract: The invention is an apparatus and method for safely depressurizing milling vials. The invention utilizes a machinist vise in communication with a pneumatic air cylinder mounted in a jig inside glove box enclosure. The invention utilizes a method for safely depressurizing milling vials. The milling vials are placed into the machinist vise inside the enclosure. The ram of the pneumatic air cylinder is placed on top of the milling vial and the pneumatic air cylinder is pressed firmly against the cap of the milling vial. Next, the air inside the enclosure is evacuated of atmosphere after which the pressure is slowly released from the pneumatic air cylinder. During this stage of the method the operator is a safe distance from the enclosure. As pressure is removed from the pneumatic air cylinder the ram is retracted and the cap of milling vial is removed.

Abstract: A radio frequency patch antenna having a radiator patch constructed of an anisotropic material, such as carbon nanotube sheet material. Such material is flexible so that the antenna may be wearable and/or integrated into a textile substrate. A feed line couples the radio signal to the patch. Furthermore, the efficiency of radiation from the patch is directly related to the orientation of the fibers or carbon nanotubes in the anisotropic material relative to the orientation of the feed line. Dual polarized radiators can be constructed from two orthogonal layers of CNT patches fed with correspondingly orthogonal feed lines.

Abstract: An electronic device in the form a two-dimensional array of nanopillars extending generally normal to a substrate is provided. The nanopillars are made from a paraelectric or superparaelectric material. In addition, a linear dielectric medium is located between individual nanopillars. A two-dimensional array of paraelectric or superparaelectric nanopillars and a linear dielectric medium form the effective dielectric medium of a paraelectric or superparaelectric varactor. In some instances, the nanopillars are cylindrical nanopillars that have an average diameter and/or average height/length between 1-300 nanometers. In other instances, the nanopillars are quasi-nanoparticles that form self-aligned nano-junctions. In addition, each of the nanopillars has a single paraelectric or superparaelectric dipole domain therewithin. As such, each of the nanopillars can be void of crystallographic defects, polycrystallinity, interactions between ferroic domains, and defects due to ferroic domain walls.
