    Abstract: Disclosed is a sensing device including a guided surface wave receive structure, a physical parameter sensor, and a radio frequency transmitter. The guided surface wave receive structure may be configured to obtain electrical energy from a guided surface wave traveling along a terrestrial medium. The physical parameter sensor may be coupled to the guided surface wave receive structure. The physical parameter sensor may also measure a physical parameter associated with a physical environment local to the physical parameter sensor. The radio frequency transmitter may be coupled to the guided surface wave receive structure and communicatively coupled to the physical parameter sensor. The radio frequency transmitter may also obtain a physical parameter measurement and transmit the physical parameter measurement over a wireless network.

    Abstract: An object identification system (400) includes a guided surface waveguide probe that produces a guided surface wave (P) that has a frequency-dependent illumination area (426) in which one or more object identification tags (402) are powered by the guided surface wave and outside of which other object identification tags are not powered by the guided surface wave; and a receiver (408) at the illumination area, the receiver receiving return signals from the one or more object identification tags located in the illumination area, the return signals emitted by the object identification tags as an automated response to being powered by the guided surface wave.
