An axially extracted virtual cathode oscillator driven by a 4 MV, 80 kA elecron beam has been used to generate microwave pulses with an average peak power of 7.5 GW at a frequency of 1.17 GHz. Peak power efficiency was 5.3% and energy efficiency was 2.3%.

    We experimentally realize an indirect coupling between two cavity modes via strong coupling with ferromagnetic resonance in Yttrium Iron Garnet. We find that some indirectly coupled modes of this system can have a higher microwave transmission than the individual uncoupled modes. Using a coupled...

    We demonstrate real-time, femtosecond-level clock synchronization across a low-lying, strongly turbulent, 12-km horizontal air path by optical two-way time transfer.
