Dr. William Chappell is director of the Microsystems Technology Office (MTO). Serving in this position since June 2014, he has focused the office on three key thrusts important to national security. These thrusts include ensuring unfettered use of the electromagnetic spectrum, building an alternative business model for acquiring advanced DoD electronics that feature built-in trust, and developing circuit architectures for next-generation machine learning. Under Dr. Chappell’s leadership, MTO is striving to develop the basic underpinnings of computation and sensing needed for an effective, information-driven military. As our daily activities rely more and more on the digital realm, these technologies will also impact society as a whole.

In the 1940s, researchers learned how to precisely control the frequency of microwaves, which enabled radio transmission to transition from relatively low-fidelity amplitude modulation (AM) to high-fidelity frequency modulation (FM). This accomplishment, called microwave frequency synthesis, brought about many advanced technologies now critical to the military, such as wireless communications, radar, electronic warfare, atomic sensors and precise timing.
The Magnetic Miniaturized and Monolithically Integrated Components (M3IC) program aims to integrate magnetic components onto semiconductor materials, improving the size and functionality of electromagnetic (EM) systems for communications, radar, and electronic warfare (EW). Current EM systems use magnetic components such as circulators, inductors, and isolators, but these are bulky and cannot be integrated with miniaturized electronic circuitry.

These thrusts include ensuring unfettered use of the electromagnetic spectrum, building an alternative business model for acquiring advanced DoD electronics that feature built-in trust, and developing circuit architectures for next-generation machine learning. MTO creates the MEMS, photonic, and electronic components needed to gracefully bridge the divide between the physical world in which we live and the digital realm where our information resides.
