    Dr. John O'Hara
    Dr. Pejman Ghasemzadeh



    Communication systems permeate all facets of everyday life and are, in a sense, the nervous system that binds together society. Examples of these communications systems include, but not limited to, cellular, WiFi, Bluetooth, near field communications (NFC), satellite communications, fiber optics communication, laser communications and visible light communications. Aspects of communication theory, networking and signal processing are used to improve the throughput, robustness, coverage and reliability of communication links and network performance.


    The research carried out by the Communication, Network and IoTs Group focuses on the key enabling technologies needed for designing and implementing future communication systems. This research thrust is focused on the analysis and design of backbone networks, including secure communications protocols and reliable links. Through 5G and beyond communication technologies, the Communications group works on building blocks of “Smart and Connected Communities”. Particular topics of current interest include cognitive radio systems (also known as software defined radio), visible light sensing and communications, millimeter- and terahertz-wave communication, Internet of Things (IoT) applications, UAV-assisted (unmanned aerial vehicle) wireless systems, and satellite communications.

    Dr. Jeffrey Young



    Radio and microwave frequency electromagnetic energy is used in numerous existing and developing technologies, such as wireless communications, radar detection and imaging, navigation, RFID, environmental sensing, and medical sensing and treatment. As new applications are developed, specialized antenna, guiding, shielding, and other structures must be implemented that are optimized for the specified use. With more and more systems relying on wireless technologies, interference between them must be understood and mitigated. Practicing engineers in RF and microwave technologies not only analyze electromagnetic radiation, propagation, and scattering, but also apply advanced statistical and signal processing techniques to design systems that will perform accurately and reliably in various different physical environments.


    The Robust Electromagnetic Field Testing and Simulation (REFTAS) Laboratory is a leader in the field of applied RF and electromagnetic frequency research. Recent projects have characterized the random electromagnetic environments in avionics bays, beneath rocket launch fairings, and below ship decks. Projects also have included airborne measurement and analysis of navigation signals, design and implementation of antenna and RFID systems, investigation of radar scattering from rough surfaces and other structures, and development of radar image processing techniques.

  • Photonics and Electro-Optics
    Dr. John O'Hara
    Dr. Daqing Piao
    Dr. Weili Zhang



    “Photonics” and “Electro-Optics” are not the most familiar words in society today, but photonic and electro-optic systems are very familiar to everyone. Such systems touch every aspect of our lives, from atmospheric imaging and advanced weather prediction, to solar power and solid-state lighting, to high-speed fiber-optical communication, to the latest technologies in laser-based health care and manufacturing. The primary research goal is to create the next generation of light-based or light-like technologies with a particular emphasis on experimental bio-photonics and terahertz research.


    The Photonics and Electro-Optics group at OSU-ECE researches the creation and analysis of next- generation optical and hybrid optical/electronic systems, with emphasis on bio-photonics, terahertz, and novel artificial materials for the manipulation of light. OSU bio-photonics researchers are using light or light-like electromagnetic radiation to advance non-invasive and minimally-invasive medical diagnostics and treatment procedures. OSU terahertz researchers are finding new ways to utilize the terahertz frequency band for 6G communications, machine-vision/imaging, and remote chemical sensing. OSU materials scientists are using ultrafast lasers to study and create new devices with fantastic properties such as non-reciprocal antennas, optical diodes, and plasmonic switches.

  • Solid State Electronics and Systems
    Dr. John Hu
    Dr. Hyusim Park


    Over decades the field of signal electronics has significantly evolved with aggressive scaling, innovative technologies, and emerging applications. Technologies such as millimeter-wave security scanners, 5G/6G communications, automotive radars, internet of things, and CubeSat data networks have become a critical part of our lives. However, this new environment has imposed stringent circuit requirements of faster speed, wider bandwidth, higher frequency, lower power consumption, higher resolution, and so on. In order to meet these requirements, designers need to not only understand principles of circuit theory, semiconductor physics, signal processing, digital design, microwave engineering, optics, but also incorporate interdisciplinary ideas (chemistry, biology, mechanical and aerospace engineering, to name a few) into their design.


    The Solid-State Electronics Group at OSU actively investigates the following main research areas: analog/mixed signal design, RF/microwave circuits and systems, terahertz sensing/communication, and extreme-environment electronics. The primary research thrust is to enable new systems and applications by designing innovative integrated circuits (ICs) using silicon, compound, or hybrid technologies.

  • Very Large Scale Integration (VLSI), Computer Architecture and Embedded Systems
    Dr. John Hu
    Dr. Weihua Sheng
    Dr. James Stine


    The revolution in communications and information technology has been enabled by semiconductor industry’s ability to manufacture integrated circuits (IC) containing millions of transistors with high reliability. Research in VLSI typically includes mixed-signal communications, digital control systems, VLSI computer architectures, and digital circuit and system design. While systems become smaller and smaller, more capabilities are being put directly onto a silicon wafer. Moreover, existing designs require excessive design costs to achieve the power, area, and performance requirements of complex system-on-chip (SoC) solutions, thus making current designs challenging and exciting. Technologies in VLSI and computer architecture allow us to manufacture power-efficient but powerful microcontrollers for a wide spectrum of embedded systems ranging from wearable devices and smart TVs, to intelligent robots and autonomous vehicles. Research in embedded systems focuses on the design, implementation and test of microcontroller-based systems for many real-world applications. 


    Research in VLSI, Computer Architecture and Embedded Systems at OSU consists of four main areas of concentration:  a) Theoretical computer architecture in search of new paradigms and instruction set architectures for application-specific and general-purpose computing, b) System-on-Chip design for application-specific areas in signal processing, communication, security, high-frequency electronics, and artificial intelligence, c) Computer arithmetic algorithms and their associated implementations related to the application and evolution of targeted optimized computation, d) wearable computing, edge computing and hardware implementation of machine learning algorithms.
