Abstract: The technology described herein is directed towards determining a phase shift matrix for an intelligent reflective surface based on active tag-enhanced sensing that provides calibrated orientation data and distance data of the intelligent reflective surface relative to a transmission-reception point, such as a radar system, base station or wireless access point. The calibration data is based on accurate estimation of element distances to the intelligent reflective surface elements. Based on the calibration data, a phase shift matrix for the elements of the intelligent reflective surface is determined. The phase shift matrix can be used in optimizing the intelligent reflective surface for redirected communications with a target. Other calibration data can be obtained at the target for element distances of the intelligent reflective surface relative to the target.

Abstract: The technology described herein is directed towards a calibration procedure for remote estimation of the position and orientation of an intelligent reflective surface. The calibration is based on accurate estimation of the relative distances between each element of an intelligent reflective surface and a transmission-reception point, e.g., radar sensor, wireless access point and/or base station. A multifrequency (e.g., dual-tone) calibration signal is transmitted to selected elements of the intelligent reflective surface, with the returned calibration signals used to determine the distance to each selected element, from which distances to other elements are determined, along with the intelligent reflective surface's orientation. An active backscatter tag that boosts the returned signal improves the distance measurement accuracy.

Abstract: The technology described herein is directed towards an autonomous reconfigurable intelligent surface (of a node) that is capable of detecting the node's surrounding environment and adjusting the redirection of impinging electromagnetic beams based on the detected environment. Real-time control of the reconfigurable intelligent surface is achieved from within the node itself, while the node consumes relatively little power. A LiDAR-based or other sensor coupled to the node provides a three-dimensional map of the environment's current state. Within the node, an AI module works with a controller to determine the phase of each reconfigurable unit-cell that forms the reconfigurable intelligent surface. The phase response of each cell redirects the impinging electromagnetic wave in the desired direction, e.g., to avoid an obstacle. This can significantly reduce coverage problems in the millimeter-wave band and even higher frequencies for beyond 5G and 6G applications.

Abstract: The technology described herein is directed towards phase-change material-based (e.g., chalcogenide) radio frequency components including for use in unit cells of a reconfigurable intelligent surface. A multi-state tunable capacitive element for reconfigurable operation is described, in which phase-change material operates as a switching element to controllably vary capacitance of each unit cell. The multi-state tunable capacitive element can be made of multiple subcircuits in which capacitors of various values can be selectively switched in or out to vary the capacitance of the tunable capacitive element. Arranging the subcircuits with capacitors of different values, and actuating each one in or out of the overall capacitive element, an analog-like variable capacitor is realized that provides more granular phase shift control of cells of a reconfigurable intelligent surface.

Abstract: The technology described herein is directed towards phase-change material-based (e.g., chalcogenide) radio frequency components that can be used in unit cells of a reconfigurable intelligent surface. A tunable device for reconfigurable operation is described, in which the operational width of phase-change material in the conductive state is controlled to controllably vary the phase shift of each unit cell. The width can be selectively controlled by heating elements that change the operational width of the material's lower-resistance state relative to its higher resistance state, resulting in a phase change of a unit cell with respect to redirecting an electromagnetic wave. By arranging the heating elements below the material, and actuating each one to provide resistive or conductive states within the overall unit cell surface, an analog-like device is provided to provide more granular phase shift control of the cells of a reconfigurable intelligent surface.

Abstract: Embodiments of the present disclosure generally relate to a multilayer stack used as a mask in extreme ultraviolet (EUV) lithography and methods for forming a multilayer stack. In one embodiment, the method includes forming a carbon layer over a film stack, forming a metal rich oxide layer on the carbon layer by a physical vapor deposition (PVD) process, forming a metal oxide photoresist layer on the metal rich oxide layer, and patterning the metal oxide photoresist layer. The metal oxide photoresist layer is different from the metal rich oxide layer and is formed by a process different from the PVD process. The metal rich oxide layer formed by the PVD process improves adhesion of the metal oxide photoresist layer and increases the secondary electrons during EUV lithography, which leads to decreased EUV dose energies.

Abstract: A monolithic radio frequency (RF) power limiter for protecting sensitive superconductor receiver components from high-power microwave signals is disclosed. In some embodiments, two low-Tc superconductor (LTS) microstrip lines; one of which is coupled with an array of RF superconducting quantum interference devices (rf-SQUIDs); are combined with a pair of hybrid couplers to provide the power limiting operation at very low RF power levels. A microstrip line coupled to an array of rf-SQUIDs behaves as a power dependent phase shifter and its phase can be controlled by the input RF power. In one embodiment, a monolithically integrated wideband hybrid coupler is used as it dictates the bandwidth of the overall device.
