    Abstract: A tunable metamaterial has a two dimensional array of resonant annular ring elements; and a plurality of voltage controllable electrical tuning elements disposed in or adjacent openings in each of said ring elements, each of said voltage controllable electrical tuning element ohmically contacting portions of only one of said ring elements. The voltage controllable electrical tuning elements may comprise highly doped semiconductor tunnel diodes, or the charge accumulation layer at the semiconductor/insulator interface of a metal-insulator-semiconductor structure, or nanoelectromechanical (NEMs) capacitors. The tunable metamaterial may be used, for example, in an optical beam steering device using the aforementioned tunable optical metamaterial in which a free-space optical beam is coupled into a receiving portion of a plane of the optical metamaterial and is steered out of a transmitter portion of the plane of the optical metamaterial in controllable azimuthal and elevational directions. The tunable metamaterial additionally has other applications.

    Abstract: The disclosed antenna structures and electronic microsystems are capable of physically disappearing in a controlled, triggerable manner. Some variations provide an on-chip transient antenna comprising a semiconductor substrate containing ion-implanted hydrogen atoms and a conductor network comprising metals bridged by low-melting-temperature metals. Some variations provide an off-chip transient antenna comprising a flexible substrate containing a polymer, nanoporous silicon particles, and an oxidant for silicon, and a conductor network comprising metals bridged by low-melting-temperature metals. Other variations provide a method of introducing physical transience to a semiconductor integrated circuit, comprising thinning a substrate from the back side, implanting hydrogen ions into the thinned substrate to introduce latent structural flaws, depositing a semiconductor integrated circuit or sensor chip, and providing a controllable heating source capable of activating the latent structural flaws. These novel approaches are compatible with existing integrated circuits processing, preserve antenna performance, and use foundry-compatible techniques.

    Abstract: An energy conversion device disposed in series with an RF driver circuit and an RF antenna, the energy conversion device being arranged to convert a portion of available RF power from the RF driver circuit into a different form of energy (direct current, thermal, or higher frequency electromagnetic waves such as light) which is converted, if needed, to DC and stored in an energy storage device coupled with the RF driver circuit for supplying recycled electrical energy thereto. The RF antenna may be an electrically small antenna and thus a antenna matching network may be provided between the RF driver circuit and the RF antenna. The energy conversion device may comprise, for example, (i) a transformer in combination with a rectifying circuit, (ii) a full wave rectifier, (iii) a half wave rectifier, (iv) a heat and/or light producing device, an energy converter (such as a generator) or a combination of the foregoing.
