Recent demonstrations of high-harmonic generation (HHG) at very high repetition frequencies (∼100 MHz) may allow for the revolutionary transfer of frequency combs to the vacuum-ultraviolet range. This ...
Since the days of pioneers like Marconi and Armstrong, radio has fascinated countless numbers of engineers. Wireless technology has evolved from the days of bulky, power-hungry vacuum tubes to today’s ...
Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...
