Electronics is focused on specialized electronic materials and devices and circuits to achieve Army dominance over the entire electromagnetic spectrum, particularly in contested environments. The two primary thrusts of this area are Energy-Efficient Electronics and Hybrid Electronics. Energy-Efficient Electronics focuses on low-power-demand electronic components having increased performance capabilities, and Hybrid Electronics focuses on high-performance semiconductor-based conformable, flexible electronics for advanced sensors and processors.
Position, Navigation, and Timing
Increase the accuracy and robustness of position, navigation, and timing (PNT) solutions for constrained applications such as dismounted soldier navigation, handheld laser designators, micro-autonomous systems, smart munitions, and missile navigation through the development of Micro-Electro-Mechanical Systems (MEMS) approaches for navigation-grade inertial measurement units (IMUs) and sensor fusion techniques to integrate optical methods, image processing, and other sensor modalities with IMUs to enhance positional accuracy.

RF Photonics consists of research and development on the generation, transportation, reception, and signal processing of RF domain signals in the optical domain for applications in Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR); Electronic Warfare (EW); and Position, Navigation and Timing (PN&T). These R&D efforts include research on novel RF-photonic materials and devices such as metamaterials that have specific 𝜺 and 𝝁 values (i.e., zero or negative) that can be used to design and fabricate optical waveguide, micro-resonator, or cavity devices that have new properties such as slow-light, high-Q, opto-mechanic effects, or environment insensitivity. We intend to design, investigate, and proof new concepts of RF-photonic subsystems such as analog correlation receivers, optical time/frequency transfer systems, optoelectronic oscillators for ultra-low-phase noise RF sources or long-holding clocks as well as RF-photonic phased-array antenna and radar systems. We will also pursue further development of semiconductor-based integrated photonic circuits so that the above RF-photonic devices and subsystems can be built in chip scale.

Microsystem Power Components
Specific research areas include:
1) Micro-scale / MEMS Power Components: High-frequency power conversion will enable fully integrated power supplies on a chip. Such power supplies are attractive for lightweight and wearable power management and distribution networks, power management for portable electronics, miniature robotic platforms, and high-efficiency antenna arrays requiring varying voltages at each element. This research area focuses on developing new, high-frequency components, enabled by MEMS and microfabrication, with low-profile and high efficiencies. The modeling fabrication and characterization of miniature power converter circuits and topologies for power supplies on chip leverages MEMS and micromachined power passive devices.
2) Heterogeneous Device Integration: Investigation of a new 3D High-Density Integration Process (3D-HIP) to create 3D stacked electronic systems compatible with diverse device technologies, substrates, and materials. 3D-HIP focuses on wafer-level packaging of heterogeneous devices with released MEMS components. Investigation of the modeling and microfabrication of MEMS power passive devices, development of fabrication processes for new power materials and devices, and development of high-efficiency materials (e.g., magnetics and dielectrics) and MEMS/micro-machined devices.
3) Wireless Power: Wireless power transfer is attractive for electronics at power levels ranging from milliwatts for body health monitoring up to kilowatts for vehicle charging, and at all levels in between. However, implementations of wireless power solutions are commonly disrupted by poor efficiency and poor adapatability in dynamic environments. New materials, circuits, and topologies are required to provide solutions that are better than the legacy power cord. For example, Soldiers are being outfitted with an ever-increasing number of electronic gadgets, each of which has unique battery requirements. An inductively coupled wireless power solution is required to distribute power from a single, centrally worn battery source to numerous electronic devices at length scales up to 1 m.

Wide Band Gap Power Electronics
Wide band gap power devices are key components for next-generation military subsystems. However, the reliability of these devices has not been well established, and the harsh operating conditions that will be typical in military applications are expected to introduce failure modes that are not critical to the commercial market. Therefore, investigation and modeling of key failure mechanisms in emerging GaN and SiC power devices and improved methods to test those devices are needed to ensure reliable operation.

Advanced Concepts for RF Antennas
As the Army moves toward multi-mission platforms, functionality of disparate radio frequency (RF) systems must be integrated into a single system. This requires planar and vertical integration of apertures, substrates, and feed networks to enable multiple modes of operation. Additive manufacturing is a disruptive technology that expands the design space for RF engineers allowing the ability to design and fabricate antennas not realizable through traditional manufacturing methods.
