Abstract

Electromagnetic field synthesis, control, manipulation, detection, and processing, in the spatial and temporal domain, are the underlying fundamental techniques that have resulted in the all-pervading technology space spanning communication, sensing, and imaging that have had a transformative impact in future 5G network. This extends from the radio-wave, millimeter-wave, and terahertz frequencies to optical fields. The development of silicon-based lithography with a nanometer-level resolution is a suitable platform to implement integrated systems for mmWave and THz applications. I will guide you through my researches in EM field synthesis by exploring new degrees of freedom in integrated circuit platforms.

First, I will present a secured mmWave directional transmitter for physical layer security.

Second, I will present a new periodic array architecture with element pattern reconfigurability to facilitate spectrally-agile arrays.

Third, I will introduce sub-wavelength EM synthesis with a 0.3 THz metasurface.

Finally, I will show an application of integrated photonic crystals to realize a physical unclonable function.
