Integrated RFIC beamforming arrays are a key enabler of high-frequency wireless systems from Ku-band to E-band. This talk discusses scalable phased-array architectures supporting shared-aperture FDD and digital beamforming, along with associated circuit, system, and calibration challenges. The discussion then extends to optical beamforming, examining photonic integrated circuit–based optical phased arrays for free-space optical communication and the architectural and algorithmic paths toward scalable two-dimensional apertures. The talk highlights common principles and challenges across RF and optical beamforming arrays

Prof. Emanuel Cohen received his Ph.D. in electrical engineering from Technion institute of technology Haifa Israel in 2012. In 2004 he joined Intel Israel, where he developed RFIC and algorithms for Wi-Fi, WiMAX and WiGig standards. Prof. Cohen joined Technion in 2015, where he is associate professor, head of the HFIC and communication lab. Current research areas include high-frequency beamforming arrays for 5G, integrated concurrent operation systems for frequency-division and full-duplex , high-speed mixed-signal for power efficiency in advanced CMOS processes and large scale silicon-photonics optical phased array for communication
