Patent number: 10976428Abstract: The present disclosure relates to an apparatus and method for synthetically making an ultra-wide imaging bandwidth in millimeter-wave frequencies, resulting in improved image resolutions to values previously unattained. The synthetic approach sums up a number of available sub-bands (channels) to build an unavailable ultra-wideband system. Each channel contains an antenna unit which is optimized for operation within that specific sub-band. The number and position of the channels can be adjusted to cover any frequency range as required for the specific application.Type: GrantFiled: February 13, 2019Date of Patent: April 13, 2021Assignee: THE TRUSTEES OF THE STEVENS INSTITUTE OF TECHNOLOGYInventors: Negar Tavassolian, Amir Mirbeik-Sabzevari

Patent number: 10935379Abstract: The present disclosure relates to a generally-applicable measurement technique based on coherent quantum enhancement effects and provides embodiments with nonlinear optics. The technique utilizes parametric nonlinear processes where the information-carrying electromagnetic quanta in a number of electromagnetic modes are converted phase coherently to signature quanta in a single mode or a few modes. The phase coherence means that while the quanta before conversion may have unequal or uncertain phase values across the modes, the signature quanta converted from those different modes have the (near) uniform phase. This can lead to significant increase in the signal to noise ratio in detecting weak signal buried in strong background noise. Applications can be found in remote sensing, ranging, biological imaging, field imaging, target detection and identification, covert communications, and other fields that can benefit from improved signal to noise ratios by using the phase coherent effect.Type: GrantFiled: November 28, 2017Date of Patent: March 2, 2021Assignee: The Trustees of the Stevens Institute of TechnologyInventor: Yuping Huang

Patent number: 10889914Abstract: The exemplary embodiments describe techniques for a controlled chemical vapor deposition growth and transfer of arrayed TMD monolayers on predetermined locations, which enable the formation of single crystalline TMD monolayer arrays on specific locations. The unique growth process includes the patterning of transition metal oxide (e.g., MoO3) on the source substrate contacting the growth substrate face-to-face, where the growth of single crystalline TMD monolayers with controlled size and location, exclusively on predetermined locations on the growth substrates is accomplished. These TMD arrays can be align-transferred using a unique process that combines the wet and stamping transfer processes onto any target substrate with a pin-point accuracy, which dramatically enhances the integrity of transferred TMDs.Type: GrantFiled: February 12, 2019Date of Patent: January 12, 2021Assignee: THE TRUSTEES OF THE STEVENS INSTITUTE OF TECHNOLOGYInventors: Eui-Hyeok Yang, Xiaotian Wang, Kyungnam Kang, Siwei Chen

Patent number: 10819081Abstract: Disclosed is a system and method for remote sensing, surface profiling, object identification, and aiming based on two-photon population inversion and subsequent photon backscattering enhanced by superradiance using two co-propagating pump waves. The present disclosure enables efficient and highly-directional photon backscattering by generating the pump waves in properly pulsed time-frequency modes, proper spatial modes, with proper group-velocity difference in air. The pump waves are relatively delayed in a tunable pulse delay device and launched to free space along a desirable direction using a laser-pointing device. When the pump waves overlap in air, signal photons will be created through two-photon driven superradiant backscattering if target gas molecules are present. The backscattered signal photons propagate back, picked using optical filters, and detected.Type: GrantFiled: January 13, 2020Date of Patent: October 27, 2020Assignee: THE TRUSTEES OF THE STEVENS INSTITUTE OF TECHNOLOGYInventor: Yuping Huang

Publication number: 20200282357Abstract: Process and apparatus are disclosed for capturing and converting an ozone-depleting alkyl halide fumigant from a fumigant/air mixed stream (14) by absorbing it into a metal hydroxide-alcohol buffer solution (26) in an absorber/scrubber (12) to produce a fumigant-free air stream. The captured alkyl halide in aqueous alcohol solution can actively react with the metal hydroxide in alcohol solution to produce a value-added product, such as a precipitate metal halide, and another alcohol that further enhances absorption. The absorbing solution is well-mixed with make-up alcohol and alkali streams to maintain the concentration of the metal hydroxide in the desired buffer solution range. The solid precipitate metal halide is separated from the liquid stream, and the metal hydroxide-containing mixed alcohol stream is recycled to the absorber/scrubber (12).Type: ApplicationFiled: September 27, 2018Publication date: September 10, 2020Applicant: THE TRUSTEES OF THE STEVENS INSTITUTE OF TECHNOLOGYInventors: Adeniyi Lawal, Lin Zhou
