Method of managing objects using an electromagnetic guided surface waves over a terrestrial medium
First Claim
Patent Images
1. A method of managing objects in a site defined by a geographic area, comprising:
- producing an electromagnetic guided surface wave along a terrestrial medium with a guided surface waveguide probe, the electromagnetic guided surface wave having sufficient energy density to power object identification tags in an entirety of the site;
receiving reply signals from the object identification tags, each object identification tag associated with a respective one of the objects; and
identifying a geolocation of one or more of the objects according to received reply signals from the object identification tags that are associated with the one or more of the objects; and
wherein the guided surface waveguide probe comprises a charge terminal elevated over the terrestrial medium and produces the electromagnetic guided surface wave by generating at least one resultant field that synthesizes a wave front incident at a complex Brewster angle of incidence (θ
(i,B)) of the terrestrial medium.

17. A method of authenticating a good, comprising:
-
producing an electromagnetic guided surface wave along a terrestrial medium with a guided surface waveguide probe, the electromagnetic guided surface wave having sufficient energy density to power an object identification tag associated with an object, the object being the good to be authenticated; receiving a reply signal from the object identification tag, the reply signal containing a tag identifier; and determining if the good is authentic by matching the tag identifier with a valid identifier stored in a database; and wherein the guided surface waveguide probe comprises a charge terminal elevated over the terrestrial medium and produces the electromagnetic guided surface wave by generating at least one resultant field that synthesizes a wave front incident at a complex Brewster angle of incidence (θ
(i,B)) of the terrestrial medium.
