from Wikipedia, the free encyclopedia

Karl Försterling, also Foersterling (born April 23, 1885 in Wernigerode , † June 20, 1960 in Cologne ) was a German physicist .

Life

Karl Försterling received his doctorate in 1909 from the University of Göttingen with a thesis on light reflection on optically active bodies. In 1914 he completed his habilitation at the Technical University of Danzig . He was tit from 1922 to 1924. Associate professor at the University of Jena and in 1924 became full professor for theoretical physics at the University of Cologne .

Försterling turned to the propagation of electromagnetic waves in inhomogeneous media and the dispersion in (conductive) plasma. In 1928 he published his textbook on optics . His dispersion formula published by Hans Lassen in 1927 is much more general and applicable than the most widely used, published in 1924 by Edward Victor Appleton .

His successor at the Cologne chair was Heinrich Lange . Försterling had been married to Dorothea Grossjohann since 1939. He died at the age of 75 in a Cologne hospital.
