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 device includes a porous substrate that include a plurality of pores and a plurality of nanodevices dispersed in at least a portion of the plurality of pores. Each of the plurality of nanodevices includes a magnetic nanowire and a solder nanoparticle. The magnetic nanowires are configured to generate heat in response to an alternating magnetic field. The solder nanoparticles are configured to receive a portion of the heat and reflow to connect to one or more devices or surfaces.

Abstract: In some examples, an antenna system includes a source antenna and a frequency selective surface (FSS) comprising a first section including a first set of horizontally oriented unit cells, a second section including a second set of horizontally oriented unit cells, and a third section between the first section and the second section, the third section including a set of vertically oriented unit cells, wherein the first section is substantially square in shape, and wherein the second section is substantially square in shape. The source antenna is configured to emit one or more electromagnetic signals through the FSS, wherein the FSS causes the one or more signals to form at least a first beam corresponding to the first section, and wherein the FSS causes the one or more signals to form at least a second beam corresponding to the second section.

Abstract: An antenna system may include a source antenna, a frequency selective surface (FSS), and a second antenna or a fluidic channel associated with a housing. In both examples, the FSS has a first side and a second side opposite from the first side. The first side includes horizontally oriented unit cells positioned as multiple columns of unit cells. The first side of the FSS faces the source antenna and is separated from the source antenna by a defined distance. The housing is positioned on the second side of the FSS. In the latter example, the fluidic channel of the housing includes one of air or deionized water. The fluidic channel is positioned on a portion of the second side of the FSS that is opposite to a subset of the horizontally oriented unit cells on the first side of the FSS.
