Devices with non-reciprocal functionalities are crucial for wireless communications, radar/imaging systems and for the growing field of quantum computing. Traditionally, these functionalities are achieved using ferrite materials biased by an external magnetic field. Unfortunately, such materials face significant challenges: they are scarcely available, and they are not compatible with existing sem ...

Nanohmics Inc. (Austin, TX), in collaboration with Prof. Dimitrios Sounas at Wayne State University (Detroit, MI), propose to continue the development of a new form of time-modulated circulators, with low loss, broad bandwidth, high isolation, and the additional advantage of full autonomy. In Phase I of the program, we explored two approaches for the design of magnet-less circulators. The first on ...

Naturally occurring protein polymers are limited by the chemistry of the canonical genetic code. By incorporating non-canonical amino acids (ncAA) monomers into proteins, the catalytic, sensing, and physical properties of proteins can be engineered to generate novel reagents and materials. To address this synthetic biology need, Fabrico Technology and Professor Andrew Ellington at the University o ...

This proposal will explore the design and fabrication of tunable nonreciprocal devices for isolation, full-duplex operation, and incorporation in topological insulators. The topologies will be based on time-modulated Wheatstone bridges of varactors connected through filters. We will explore using dual-mode filters that provide independent control over the common and differential modes of the circu ...

This proposal investigates nonlinear metasurface technology that exploits sharp Fano-resonances to engineer energy and size efficient photonic devices that perform better than the state-of-the art isolators, switches, and modulators. To circumvent the fundamental bounds of performance with single Fano-resonator isolators, this work will demonstrate novel isolators comprising of two stacked Fano-me ...

This Small Business Innovation Research (SBIR) Phase II project will perform some needed tests for commercialization of the highly PFAS-selective nanofiber mats fabricated from electrospun polymer nanofibers. The Phase I results have shown the proof of concept for two materials developed for the removal of PFOA and PFOS with over 91% efficiency at very high concentrations (ppm level) and 99% at lo ...

Fats, oils and greases (FOGs) cause 75% of sewer systems in the US to operate at 50% capacity, cost US cities over $20 billion in sewer maintenance, and cause over 40,000 sewer overflows annually. Most commercial kitchens are required by law to remove FOGs with a grease interceptor from wastewater before emitting into public sewers. In order to reduce sewer maintenance costs and overflows while in ...

We propose a quantum adversarial machine learning (QAML) approach that combines ideas from different classical AML techniques such as Defense-GAN and thermometer-encoding of inputs. We propose an implementation of Defense-GAN on the D-Wave Leap quantum computing environment. We also propose to leverage ideas from quantum information science such as noisy inputs/outputs/parameters to improve the ro ...

The development of a guided hypervelocity projectile (HVP) must surmount a number of significant technical challenges. Texas Research Institute Austin (TRI Austin) proposes to address leading edge/control surface challenges, sabot design, and the sub-projectile issues through the selection of materials, material processes, and component manufacturing methods. TRI Austin has assembled a team of tec ...
