Abstract: The techniques and systems described herein relate to manufacturing, characterizing, and/or identifying one or more types of magnetic nanowires (MNWs). One or more types of MNWs may be associated with different objects, and a system may identify the objects based on the magnetic nanowires associated with the objects. For example, such techniques may involve characterizing the types of MNWs based on magnetic field transmission characteristics and ferromagnetic resonance characteristics of each type of MNW. In some examples, the techniques described herein may enable the identification of each of a plurality of types of MNWs present in a sample or object based on a combined transmission value of the sample. Such techniques may enable the development and use of barcode-like systems of different types of MNWs for labeling and identifying objects of interest.

Abstract: A segmented radio antenna that uses electrically conductive quick connect/disconnect devices between segments to accomplish a conversion from efficiency on one band to efficiency on another band AND/OR to convert quickly and easy between center-fed and end-fed (or a variety of feed-point configurations).The innovative use of flexible wire segments and connectors reduces the overall weight and cost of the antenna when compared to the use of traps or telescoping antennas.

Abstract: A low RCS array panel employs a number of linkable support segments. Each support segment has several junctions spaced along it, and the support segments are designed to connect with each other at the junctions to create a support grid. The segments can connect orthogonally, and the junctions can be spaced according to the frequency performance requirements for the antenna the array panel is designed to support.

Abstract: A compact antenna assembly which includes a lower member having a mast that is an elongated configuration terminating at an upper end and a lower end. The mast can be located at the center of an upper member. The upper member includes an emitter, having a perimeter, a top end, and a bottom end. The upper end of the mast is electrically connected to the perimeter near the top end. Furthermore, a collector with a centrally disposed opening can be placed in a horizontal plane which positions the collector orthogonally in space with respect to the mast so that the collector is electrically insulated from the emitter and the mast. The lower end of the mast is centered at the centrally disposed opening of the collector and extends perpendicularly to the plane of the collector.

Abstract: A dual mode broadband antenna especially designed to provide an omni-directional low angle or high angle radiation pattern which is predominately horizontally polarized is disclosed herein. This antenna utilizes four wire radiators in the form of an inverted conical log-spiral supported in a vertically extending fashion a predetermined distance above the horizontal ground plane. In order to alternatively operate the antenna in its high and low angle modes, first and second oppositely phased AC currents are applied to the radiators in two different ways using a simple switching device rather than a more complicated network of four hybrid circuits.

Abstract: An RFID device includes an antenna defining a gap, with an RFID chip electrically coupled to the antenna across the gap. The RFID chip may be incorporated into an RFID strap, in which a pair of connection pads is connected to the RFID chip, with the connection pads connected to the antenna on opposite sides of the gap. Alternatively, the antenna may be connected to bond pads of the RFID chip. At least a portion of the antenna has a cross section with an at least partially curved perimeter. The cross section of the antenna may be differently shaped at different locations, such as having a flattened oval shape at one location and a substantially circular shape at another location. A portion of the cross section of the antenna may have a non-curved, relatively sharp edge, which may break through an outer oxide layer of a connection pad.
