1 NIKOLA TESLA - GENIUS WHO INVENTED the TWENTIETH CENTURY Aleksandar Marinčić

2 Profesor Robert Lomas, Bradford University: Nikola Tesla – Forgotten Genius of Electricity, 1999.

3 YU-MTT Chapter issued a periodical Microwave Review Vol. 2, No. 7, 2001 Dedicated to 145 th Anniversary of Nikola Tesla

4 Participants from abroad: Prof. Jasmina Vujić, California University, Berkeley Dr Đurađ Budimir, Westminster University, London K.L. Corum, Dr J.F. Corum USA John W. Wagner Elementary School, USA

5 Radio development James Clerk Maxwell - electromagnetic waves (theoretical prediction, 1865.) Heinrich Hertz - experimental verification of Maxwells theory (1888.) Nikola Tesla – continuous wave Oliver Lodge -wireless telegraph (1894.) G. Marconi – modification of Hertz apparatus (1896.)

6 Hertz transmitter (1887)

7 Teslas contributions to radio development Generators of h.f.currents – machine and spark generators (Tesla coil), Coupling of generator to antenna – ground system (1892./3.) System of four tuned circuits, Receiver with rectification of h.f. current and integration and damp, Using two (or three) carriers to provide protective coding and suppression of interference and receiver with AND circuit 1900.

8 Teslas lecture at Columbia College, 1891
