Abstract:

The opening of new spectrum in the millimeter-Wave and Terahertz frequency from  28GHz-100 GHz and extending up to 1000 GHz is expected to serve as the backbone for future wireless infrastructure and enable new form of sensing and imaging modalities for future autonomous systems, and for applications in biochemical and . These two frequency domains, while contiguous in spectrum, operates in fundamentally different regions with respect to the integrated device performance; one exists below the device cut-off frequency and one exists above it. This leads to fundamentally different techniques in architectures, but the common features for integrated system operating in these regimes is the need for universality and reconfigurability. 

As disjointed spectral bands open up across 28-100 GHz for 5G applications and beyond, spectrally agile, robust mmWave front-ends that can allow dynamic reconfiguration in large scale mmWave MIMO arrays can have a transformative impact in spectrum efficiency and deployment of such 5G systems. Such properties are also critically important for applications in sensing and imaging at THz, as evidenced across sensor fusion technologies across mmWave, IR and optical frequencies. The ultimate programmability in any of such wireless interfaces is one that can synthesize or receive THz fields with arbitrary configuration and spectrum. In this talk, I will highlight approaches that cut across electromagnetics, circuits, systems and signal processing, to allow for such reconfigurability in mmWave/THz signal synthesis and sensing (Nat. Elect’18, Nat. Comm’19), yet realized with devices that are themselves not very efficient. Incorporating, such programmability across the three field properties of spectrum, beam pattern and polarization, I will comment on what could be the major directions for the field in the coming decade.
