Photonic band gap materials comprising positive-phase-velocity and negative-phase-velocity layers in waveguides
(Taylor & Francis Ltd, 2009-09)
We have analyzed electromagnetic wave propagation in photonic bandgap (PBG) structures comprising alternating layers of isotropic dielectric-magnetic materials with positive phase velocity and negative phase velocity, ...
Pressure field in the cathode-anode region of a high-power klystron amplifier
(2004-08-30)
The pressure field of a high-power klystron amplifier in the cathode and anode region was investigated. The investigation was performed using a 1.3 GHz, 100 A and 240 kV high-power klystron with five reentrant coaxial ...

Pressure field along the axis of a high-power klystron amplifier
(Institute of Electrical and Electronics Engineers (IEEE), 2003-01-01)
The pressure field in a high-power klystron amplifier is investigated to scale the ionic vacuum pump used to maintain the ultra high-vacuum in the device in order to increase its life-time. The investigation is conducted ...
