"On-chip and multiplexed metasurfaces for light manipulation" Abstract: Metasurfaces, which consist of two-dimensional subwavelength nanostructures that can locally manipulate the proprieties of light including amplitude, phase, and polarization, provide an unprecedented means to control optical waves in a prescribed manner. Different functionalities, such as structured light, holograms, and flat lenses, have been realized by metasurfaces. […]
The NSF sponsored Nano Systems Innovation (NanoSI) workshop will conduct a deep dive into infrastructure requirements to enable a unique national infrastructure for piezoelectric and hetero-integrated nano systems. The virtual workshop will bring together researchers, government, industry and foundry partners to identify the emerging needs for adaptable infrastructure that can address national research priorities in […]
"Robust Data-Driven Control" Abstract: During the last two decades, data-driven control (DDC) has attracted growing attention in the control community. Unlike model-based control (MBC), which first uses the collected data to identify the system, then designs the controller according to the certainty equivalence principle, DDC skips the system identification (SYSID) step and leads to a […]
"RF Front-End Components based on Linear-Time-Variant Modulation of Piezoelectric MEMS Resonators" Abstract: Throughout the last decade, radio frequency (RF) components for over-the-air communication and sensing have been subject to sustained market pressure to adapt to the novel trends such as spectrum sharing, programmability, and low-power operation. When these features are required in chip-scale RF hardware, […]
"Theory and design of spatiotemporally-modulated metasurfaces for comprehensive control of light" Abstract: Photonic metasurfaces are key platforms for manipulating almost all properties of light such as amplitude, phase, polarization, wave vector, pulse shape, and orbital angular momentum in a sub-wavelength dimension. They are capable of providing unprecedented modulation of wavefront through imparting spatial or temporal […]
Location: ISEC 332 "Towards Reliable, High Capacity mmWave Wireless LANs for Mobile Devices" Abstract: The IEEE 802.11ad standard, with its 14 GHz of unlicensed spectrum around 60 GHz, is touted as one of the key technologies for building the next generation of WLANs that will enable high throughput demanding mobile applications. However, there have been serious […]
"Development of Anomaly Detection and Characterization Algorithms Using Wideband Radar Image Processing for Security Applications" Abstract: Detection and characterization of suspicious body-worn objects is necessary for safe and effective personnel screening. In airports, developing a precise system that can distinguish threats and explosives from objects like money belt can reduce the pat-down significantly while maintaining […]
"AlN/AlScN based Micro Acoustic Metamaterials for Radio Frequency Applications of the Next Generations" Abstract: In the last two decades‚ micro-acoustic resonators (μARs) have played a key role in integrated 1G-to-4G radios‚ providing the technological means to achieve compact radio frequency (RF) filters with low loss and moderate fractional bandwidths (BW<4%). More specifically‚ Aluminum Nitride (AlN) […]
