摘要： A modular radio frequency (RF) device includes N base units, each including a differential segmented array (DSA) tile with a support board and a two-dimensional (2D) array of electrically conductive tapered projections disposed on the support board. Neighboring pairs of the electrically conductive tapered projections form RF pixels. The N DSA tiles are arranged to form an RF aperture. The N base units are programmed to switch the RF aperture between a first operating mode and a second operating mode. In the first operating mode, the N base units are operated as at least two independent subsets with each subset operating as an RF transmitter or receiver independently of the other subsets. In the second operating mode all N base units coherently combine as a single phased array RF transmitter or receiver.

摘要： A broadband RF imaging device includes a broadband RF aperture array, at least one RF receiver, and a computer. The at least one RF receiver has short RF connections with the broadband RF aperture array, e.g. length 10 meters or less. The computer has a digital data connection to the at least one RF receiver. Each RF receiver is configured to receive broadband RF signal data over a sampling time interval from the broadband RF aperture array, and to digitize the broadband RF signal data to generate digitized broadband RF signal data, and to store the digitized broadband RF signal data locally at the RF receiver. The computer receives the digitized broadband RF signal data stored locally at the at least one RF receiver, and is programmed to reconstruct an RF image from the digitized broadband RF signal data received from the at least one RF receiver.

摘要： A radio frequency (RF) aperture includes an array of electrically conductive tapered projections arranged to define a curved aperture surface, such as a semi-cylinder aperture surface, or a cylinder aperture surface (which may be constructed as two semi-circular aperture surfaces mutually arranged to define the cylinder aperture surface). The RF aperture may further include a top array of electrically conductive tapered projections arranged to define a top aperture surface. The top aperture surface may be planar, and a cylinder axis of cylinder aperture surface may be perpendicular to the plane of the planar top aperture surface. The RF aperture may further include baluns mounted on at least one printed circuit board, each having a balanced port electrically connected with two neighboring electrically conductive tapered projections of the array and further having an unbalanced port.

摘要： A radio frequency (RF) aperture includes an interface board. An array of electrically conductive tapered projections have bases disposed on a front side of the interface printed circuit board and extend away from the front side of the interface printed circuit board. RF circuitry is disposed at the back side of the interface board and is electrically connected with the electrically conductive tapered projections.

摘要： A fuel processing system and method for a sulfur bearing fuel include a hydrodesulfurization reactor followed by an adsorbent bed for removing sulfur or sulfur containing species from the fuel. In certain embodiments, the adsorbent bed is a ZnO bed. In another embodiment, a fuel processing system and method for a sulfur bearing fuel include a steam reformer, a hydrodesulfurization reactor, and an adsorbent bed.
