Photophysical transformations in molecules studied by ultrafast multi-pulse spectroscopy /
… systems by the means of transient absorption spectroscopy. First two chapters are dedicated to the theoretical background, the description of the objects of the study and the experimental tools used. The following three chapters correspond to three different systems explored by ultrafast …

A low-cost pulsed Fourier transform network analyzer.
… This thesis documents the development a low-cost pulsed Fourier transform network analyzer which can be used to measure the electrical properties of materials. New silicon-germanium integrated circuits allow for the pulse system to be implemented for under $300.

Development of a ferroelectric plasma source through material degradation studies and characterization of volume and surface discharges
… large surface currents (10^0 – 10^5 A/cm2), is pulsed to emit electrons and ions. The ferroelectric material uniquely affects emission, which in turn uniquely affects the ferroelectric surface. Lifetimes are typically limited to 10^4 to 10^5 emissions due to poorly understood degradation …
