After the first WPT trial, the history of radiowaves has been dominated by wireless communications and remote sensing. On the basis of development of microwave tubes during World War II, W.C. Brown introduced the first microwave power transfer (MPT) research and development in the 1960s. ...

Guglielmo Marconi is known as the father of radio. Marconi was an Italian inventor that proved that communicating through radio waves was possible. In 1865 he sent and received the first radio signal communication. On December 12, 1901 he flashed the first wireless radio signal across the Atlanti...
Further experiments revealed that the pattern of the electrons was determined by the crystal structure of the nickel target, not the intrinsic atomic structure of nickel. Comparison with the energies of X-rays striking the same target indicated that the electrons were behaving as waves, not ...
Beginning at the early days of spark-gap transmitters, this tale touches on the emergence of radio and television broadcasting, as well as radio navigation and radar, before moving on to the rise of satellite, near-field and light-based communications. Finally, the development of wireless home ...
Radio waves are amazing things. We can’t see them. We can’t feel them. Yet, much of the world runs on electromagnetic radio waves. If you are listening to this on a smartphone, you probably downloaded this podcast via radio waves. ...
