    摘要: An photonic RF circulator is described that provides greater than 40 db of isolation between a Received RF signal and a Transmitted RF signal in a simultaneous transmit and receive device. The photonic RF circulator uses light modulated in an optical waveguide grating where the Received RF signal co-propagates with the light and the Transmitted RF signal counter-propagates with the light. Variations described within provide for broadening the bandwidth of the T/R isolation and rejection of various noise sources.

    摘要: 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.

    摘要: This invention is the Optically Powered and Controlled Non-Foster Circuit (OPCNFC) that is electrically floating; i.e., it does not have any metallic electrical/conductive connection to a power supply, ground, or control signal. Rather power and control signals are applied to the OPCNFC using optical energy. The Non-Foster Circuit (NFC) synthesizes negative inductance, negative capacitance, and/or negative resistance between metallic patches disposed in an array of an Artificial Impedance Surface (AIS).
