Travelling-Wave Tubes TRIZ Cases
- Integrated Slow-Wave Structure for Consistent TWT Manufacturing
A monolithic slow-wave line and support structure cuts TWT assembly errors, shortens production cycles, and improves yield and consistency.
- Folded Waveguide Slow-Wave Structure for Wideband TWT Stability
Gradually varying folded waveguide amplitude and cycle cuts reflection and backward-wave oscillation while widening TWT bandwidth.
- Dielectric-Coated Plasmonic Photoemitter for Low-Field Tunneling
An atomically thin dielectric coating boosts nanotip optical fields and current density, enabling photoemission at much lower laser intensity.
- Microwave Tube Power Supply Switching for Faster Restart
During voltage dips, stored power is cut to the anode but kept on the heater, preserving cathode temperature and shortening microwave tube restart time.
- Self-Assembled Slow-Wave Helix for Terahertz TWT Fabrication
Strain-relaxed film rolling forms precise slow-wave helices for wafer-level terahertz TWT fabrication, reducing alignment limits and signal loss.
- Meander Slow-Wave Circuit Layout for Low-Loss Terahertz Gain
A protruding beam-hole layout in a meander slow-wave circuit cuts energy loss and phase-velocity dispersion while widening terahertz amplification bandwidth.
- Crossed-Field Amplifier Anode Cathode Geometry for Spurious Emission Reduction
Adjusting anode-to-cathode spacing and cathode radius increases electron diffusion, reducing peak spurious emission amplitudes by 6.5 dB.
- Segmented Cathode for Phase-Stable Planar Magnetron
Segmented cathode gaps align with anode cavities to synchronize phase in even pi modes, resolving weak coupling and frequency drift.
- Electron Gun Cathode Through Hole No-Emitting Layer
A cathode with a through hole applies a no-emitting layer to prevent dark current and protect the electron beam from disturbance.
