Patent number: 9646241Abstract: An electromagnetic radiation decoupler for decoupling radiation in the wavelength range ?min to ?max. The decoupler has a first conductor layer in contact with a dielectric layer which comprises at least one area of absence and the thickness of the decoupler is less than ?min/4n, where n is the refractive index of the dielectric. The dielectric layer may be sandwiched between two conductor layers, one of which has the structure described above. The invention is also directed to methods of using and various articles comprising such a decoupler.Type: GrantFiled: June 26, 2015Date of Patent: May 9, 2017Assignee: OMNI-ID CAYMAN LIMITEDInventors: Christopher Robert Lawrence, Paul Richard Clarke, James Robert Brown, William Norman Damerell

Patent number: 9590306Abstract: Apparatus and methods for providing a substantially surface independent tagging system are disclosed. A resonant dielectric cavity is defined between upper and lower conducting layers, and closed at one end by a conducting base portion. Incident radiation couples into the cavity and is resonantly enhanced. An electronic device or tag paced at the edge of the cavity experiences a high electric field strength on account of this enhancement and is driven into operation.Type: GrantFiled: November 17, 2015Date of Patent: March 7, 2017Assignee: OMNI-ID CAYMAN LIMITEDInventors: James Robert Brown, Christopher Robert Lawrence
