Adrianus Teunis (Aad) de Hoop (born 24 December 1927) is a Dutch electrical engineer, mathematician, and physicist, and professor emeritus at Delft University of Technology.

[1] De Hoop's research interests are in the broad area of wavefield modeling in acoustics, electromagnetics, and elastodynamics.

He spent a year in 1956 as a research assistant at University of California's Institute of Geophysics in Los Angeles in the United States.

This modification was later called the Cagniard-de Hoop method and is now considered a benchmark tool in analyzing time-domain wave propagation.

[1] Since 1982, De Hoop has been a regular visiting scientist at the Schlumberger-Doll Research Center, formerly located in Ridgefield, Connecticut and now in Cambridge, Massachusetts in the United States.
