The principal objective of the Electronics Program is to generate new fundamental knowledge of electro-magnetic, photonic, acoustic devices, systems, and phenomena in order to provide technological superiority to the Army's future force. This program will identify and solve the Army's critical basic research problems where progress has been inhibited by a lack of novel concepts or fundamental knowledge. Electronics are relevant to nearly all Army systems. Recently supported electronics research can be divided into five application areas: Multimodal Sensing, Ubiquitous Communications, Intelligent Information Technology, Power Electronics, and Electromagnetic Warfare.
The Electronics Division supports the following research areas:
Dr. David M. Stepp (A)
Nano and Bioelectronics
Dr. Joe Qiu
This research area emphasizes efforts to discover and create unique phenomena at the nanoscale with the use of nanoscience, bioscience, and the combination thereof in an effort to provide novel electronic technological capabilities for defense-related applications such as sensing, data acquisition, information processing, communications, target recognition, and surveillance.
A research program involving quantum phenomena, internally and externally induced stimulus, and novel transport and optical interaction effects in nanoscale electronic structures and which incorporates these effects into devices and systems with an enhanced degree of functionality and performance. This fundamental research addresses issues related to design, modeling, fabrication, testing and characterization, and includes the ability to individually address, control, and modify structures, materials and devices, as well as the assembly of such structures into systems of nano and microscopic dimensions. This research seeks to discover and develop novel electronic materials, advance processing and fabrication science, and identify advanced device concepts. It also includes quantum-confined structures (nanotubes,nanowires and nanodots), nonequilibrium and dissipative processes in low-dimensional structures, contacts and interconnects, and advanced synthetic and/or hybrid electronic materials. The program will involve the creation of novel electronic devices including nano- and bio-based sensors and transducers based on semiconductor electronics and hybrid molecular-semiconductor devices in addition to organic-inorganic hybrid materials. Whereas the primary emphasis is on nanotechnology, an important element is bioelectronics, encompassing the study of electronic aspects of biological and biomimetic structures, processes, and architectures. This includes the study of nano and biointerfaces in materials and structures such as that between neurons and electronic material. Another area of interest is the investigation of bio and nanopower generation and transmission including biological or bio-inspired energy generation.
Electromagnetics and Radio Frequency Electronics
Dr. Joe Qiu
This program area is concerned with the investigation of electromagnetic (EM) and radio frequency (RF) phenomena for integrated antenna arrays, multifunctional antennas, EM power distribution, and new sensing modalities. It also explores acoustic phenomena and new concepts for circuit integration for greater functionality, smaller size/weight, lower power consumption, and enhanced performance, with focus in the frequency regime from low to terahertz frequencies.
This area addresses the science behind new approaches to the generation, transmission, and reception of EM power and signals. Emphasis is placed on the HF through terahertz spectrum; however, novel ideas at lower frequencies down to direct current may be addressed. In the RF regime orders of magnitude improvements in systems performance, cost, weight, reliability, size characteristics, and functionality will be sought. Issues include the coupling of EM radiation into and out of complex structures, antennas, both active and passive, transmission lines and feed networks, power combining techniques, EM-wave analyses of electrical components, and EM modeling techniques. Thermal problems stemming from the concentration of higher and higher power into smaller and smaller volumes will be addressed. Antenna research will break away from the methodologies that were developed for continuous-wave, narrowband, steady-state operation to invent new design techniques, architectures, and materials that can dramatically increase the radiation efficiency and bandwidth of tactical antennas while simultaneously reducing their size and signature. The EM and acoustic detection and analysis of underground targets, landmines, and IED's will continue to be of interest. Unusual propagation effects in the atmosphere and gaseous plasmas offer new opportunities for sensing and detection. Army applications of this technology include communications (both tactical and strategic), command and control, reconnaissance, surveillance, target acquisition, and weapons guidance and control.
