Detection of fecal indicating bacteria plays an important role in water quality monitoring to ensure safe human water contact and/or drinking. Specifically, epidemiological studies by the U.S. Environmental Protection Agency (EPA) have shown strong correlations between illnesses and bacteria concentrations of Enterococci and E.
Drs. Yoon, Xie, Arnold, Sheplak lead research focused on advanced electromagnetic and photonic devices and systems. Examples include micro-/nano machined metamaterials, RF components, optical transducers, and wireless systems. Metamaterials--artificial materials designed for microwave, terahertz, or optic frequency bands--are being developed to enable compact radio frequency (RF) components; multiband microwave filters, resonators, and couplers; subwavelength lenses; and cloaking devices. Additional effort is focused on micromachined electromagnetic components such as antennas, waveguides, inductors, and transformers. Optical-based sensors/actuators/systems are being leveraged for measurements in harsh environments or for in vivo biomedical imaging. Lastly, wireless sensors and systems are being explored for remote sensing and wireless power transmission.
