Ingrid Wilke joined RPI's Department of Physics, Applied Physics & Astronomy as a faculty member in 2002. Prior to her appointment at RPI, she spent seven years as a senior research associate (C1) at the University of Hamburg's (Germany) Institute of Applied Physics. She has done post-doctoral work at both the University of Tokyo's Institute of Industrial Science and at the Lawrence Berkley National Laboratory, Materials and Chemical Science division. Her research areas are: Time-domain Terahertz (THz) spectroscopy, Ultrafast spectroscopy and applications of femtosecond laser pulses.
Ingrid Wilke's primary research focus is experimental terahertz (THz) wave science and technology as well as ultrafast laser applications. Terahertz wave technologies are materials, devices, systems and processes involving THz frequency electromagnetic waves. Terahertz waves are invisible to the human eye. In our solar system, the Sun is a natural source of THz waves. Broadly, THz waves are employed for spectroscopy, imaging and sensing. Her research specifically addresses the development of photonic THz radiation sources detectors and systems. Another specific area of research interest is the response of natural and artificial materials when exposed to THz waves.
Experimental Methods: Time-domain THz-emission measurements, time-domain THz transmission and reflection spectroscopy, phase-sensitive backward wave oscillator based THz-spectroscopy, femtosecond optical transient reflectivity and transmittivity measurements, femtosecond optical four-wave mixing, femtosecond laser nanoprocessing of living cells and fluorescence microscopy.
Materials of interest: Natural inorganic and biological materials, e.g. clay minerals, biological tissue, semiconductors, superconductors, dielectrics, glasses, ceramics.
