Radar Waveform Design and the Heisenberg Group
Applied and Computational Harmonic Analysis, 1995 The paper under review is in the spirit of a recent paper on the deformation theory of radar ambiguity functions published by the same authors [Weyl multipliers. J. Fourier Anal. Appl. 2, 191-215 (1995)]. It begins with a presentation of the Heisenberg group theoretic setting [\textit{W. Schempp}, Radar reception and nilpotent harmonic analysis. I--IV.

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.
