摘要： An optical construction includes optical stacks arranged across the construction and spaced apart from each other. Each of the optical stacks has a transmittance of at least 60% for at least one visible wavelength and includes one or more electrically conductive layers. The optical stacks are co-extensive with first and second antennas. Each of the electrically conductive layers defines a through opening aligned with at least one of the first and second antennas. For each of an s-polarized first incident signal incident on the optical construction in a first incident plane and a p-polarized second incident signal incident on the optical construction in a second incident plane orthogonal to the first incident plane, for at least one frequency in a range from 0.5 GHz to 10 GHz, and for incident angles of up to 40 degrees, the optical construction has a transmission coefficient of between 0 dB and −10 dB.

摘要： A patterned article includes a unitary polymeric layer and a plurality of electrically conductive elements embedded at least partially in the unitary polymeric layer. Each electrically conductive element includes a conductive seed layer having a top major surface and an opposite bottom major surface in direct contact with the unitary polymeric layer, and includes a metallic body disposed on the top major surface of the conductive seed layer. The metallic body has a bottom major surface and at least one sidewall. The bottom major surface contacts the conductive seed layer. Each sidewall is in direct contact with the unitary polymeric layer and extends from the bottom major surface of the metallic body toward or to, but not past, a top major surface of the unitary polymeric layer. The conductive elements may be electrically isolated from one another. Processes for making the patterned article are described.

摘要： A tracker device for a first responder including a radio configured to receive a first radio signal from an emitter, and receive a second radio signal from an unmanned aerial vehicle (UAV). The second radio signal includes at least one data packet including location information associated with the emitter. Processing circuitry in communication with the radio is configured to determine at least one location parameter associated with the emitter based on the first radio signal and the location information of the at least one data packet of the second radio signal.
