Latest Patents

Serfaty is credited with 1 patent: “Apparatus of Multifrequency Electromagnetic Resonators Inductively Coupled to One Another Forming an Array of Resonators or a Metamaterial, and Implementation Method.”

The patent describes an array of individual passive resonators that are not electrically connected. Each resonator consists of interrupted transmission lines that loop back on themselves, with nested groups of parallel tracks. The resonators are paired without physical contact around one or more dielectric substrate layers.

The array can modify an incident magnetic or electromagnetic field and support impedance matching when placed between the field and an object being treated or observed. The invention also describes contactless characterization of a medium, using inductive coupling between array resonators and a probe connected to a reader.
