Abstract
Official abstract text for this publication.
Systems and methods for detecting electromagnetic waves are disclosed. A system for use in detecting an electromagnetic wave includes an inductive device and a spintronic device. The inductive device generates an induced electromagnetic field when the inductive device receives the electromagnetic wave. The spintronic device has an impedance that changes when exposed to the induced electromagnetic field from the inductive device. The change in impedance is indicative of the electromagnetic wave received by the inductive device. Another system for use in detecting or transmitting an electromagnetic wave includes a conductive device and an inductive device. The inductive device is configured to generate an induced electromagnetic wave when the inductive device receives an electromagnetic wave passed by the conductive device. Another system for detecting electromagnetic wave permittivity or permeability of an object includes a pair of antennas and an inductive device.
