Abstract: A true random number generator including a transistor, a first voltage source, a second voltage source, and a comparator. The transistor has a first electrode, a second electrode, and a third electrode. Two of the electrodes are electrically connected by a channel of conductive nanomaterial. The first voltage source is electrically connected to the first electrode and the second voltage source is electrically connected to the second electrode. The comparator is electrically connected to the third electrode and is configured to classify a measured electrical property at the third electrode as either HIGH or LOW based on a comparison of the measured electrical property with a reference value. The measured electrical property varies over time due to random telegraph signals (RTSs) due to defects in the transistor.

Abstract: A switchboard controller for a parasitic antenna array. The switchboard controller has an internal bias tee mounted within an RF-shielded enclosure. The internal bias tee has an RF port, a DC port, and an RF & DC port. The RF port is configured to be connected to a driven element of the parasitic array antenna, and the RF & DC port is configured to be connected to an RF and DC source. The switchboard controller also has a voltage regulator mounted within the enclosure and is electrically connected to the DC port. The switchboard controller also has a plurality of manual switches electrically connected to the voltage regulator, each switch operatively connected to a separate parasitic element of the parasitic array antenna. The switches are mounted on the back side of a frame in a 2-dimensional pattern that is similar to the physical layout of the parasitic elements.

Abstract: A phased array antenna comprising: a substrate; a plurality of circular polarized wideband antenna elements disposed on the substrate, wherein each element comprises two orthogonal feeds; wherein the plurality of elements are organized into subarrays and physically oriented such that constituent elements of each subarray are sequentially rotated with respect to each other about respective axes that are perpendicular to a surface of the substrate so as to allow RHCP and LHCP transmission and reception; a phase shifter communicatively coupled to the feeds of all the elements and configured to electronically any dynamically compensate for phase regression or progression introduced by the sequential rotation of the elements without relying on physical transmission lines of different dimensions, and further configured to introduce a progressive phase shift across a beam steering plane to enable beam steering of the phased array antenna.

Abstract: A method for using a graphene field-effect transistor (GFET) as a reconfigurable circuit, the method comprising the following steps: depositing a liquid dielectric over a graphene channel of the GFET; applying an activation energy via a first electric field across the liquid dielectric and the graphene channel to electrochemically produce chemical species within the liquid dielectric such that the chemical species accumulate at, and molecularly bond with, the graphene channel thereby decreasing a conductivity of the graphene channel; and applying a deactivation energy via a second electric field of opposite polarity to the first electric field to remove interaction between the chemical species and the graphene channel to increase the conductivity of the graphene channel.
