Patents During his career, Leonard Lewin authored and was granted 40 patents.
Awards In 1962, Lewin was awarded the Microwave Prize by the IEEE Microwave Theory and Techniques Society. In 1967, The University of Colorado awarded Lewin an Honorary
Doctorate of Science (D.Sc.). In 1981, Lewin became a
Fulbright scholar, and he lectured in
Austria,
Turkey and
Yugoslavia. In 1981 and 1990, Lewin lectured at the
École nationale supérieure des télécommunications in
Paris,

University of Auckland in
New Zealand. He was also invited to speak at the 1990
International Congress of Mathematicians in
Kyoto,
Japan. In 1991, Lewin lectured at the
Max Planck Institute for Mathematics in
Bonn,
Germany. In 1993, after his retirement, Lewin received the Microwave Career Award from the
Institute of Electrical and Electronics Engineers (IEEE) Microwave Theory and Techniques Society.
