Ingrid Wilke's primary research focus is on 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 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-wave emission measurements, time-domain TH-wave transmission and reflection spectroscopy, phase-sensitive backward wave oscillator based THz-wave spectroscopy, femtosecond optical transient reflectivity and transmittivity measurements.

Materials of interest: Natural inorganic and biological materials, e.g. clay minerals, biological tissue, semiconductors, superconductors, dielectrics, glasses, ceramics, gases.
