Radoslav Horvat and Mirko Mlić, founders of Circuit Theory in former Yugoslavia

Professors Radoslav Horvat and Mirko Milić taught theory of electrical circuits in the Faculty of Electrical Engineering at the University of Belgrade during the second half of the 20^th century. They introduced the most up-to-date topics in their courses and for decades educated thousands of engineers and scientists. They established a well-known “School in Theory of Electrical Circuits” that was recognized worldwide. As prominent educators and scientists, they left a profound trace in broad spectrum of topics in the area of circuit theory and were considered to be founders of circuit theory in former Yugoslavia. This paper is a brief overview of their fruitful and long-lasting contributions.
