RF, Electromagnetics & Acoustics research spans the generation, manipulation, transduction, and detection of electromagnetic and acoustic waves across an exceptionally broad frequency range—from infrasound and audio acoustics, through radio, microwave, millimeter, and terahertz frequencies, to mid-infrared and visible wavelengths. The critical scientific and engineering challenge of this research thrust is to engineer devices, materials, and systems that achieve high efficiency, low loss, and selective coupling across these widely separated regimes, while integrating heterogeneous electronic, photonic, phononic, and magnetic phenomena on a common platform. Advances in this area have applications in wireless communication and radar, RF front ends and signal processing, high-resolution sensing and spectroscopy, biomedical and harsh-environment instrumentation, neuromorphic and quantum computing, and emerging photonic, phononic, and spintronic information processing. The University of Texas at Austin has strong research expertise in piezoelectric and acoustic microsystems, integrated photonic and microwave devices, long-wavelength photonic sources and frequency combs, theoretical and computational electromagnetics, hybrid quantum and photonic-phononic transduction, and nanostructured semiconductor and spintronic devices for RF and millimeter-wave applications.
