Short Antennas For Non-Sinusoidal Waves TRIZ Cases
- Bipolar VIG Pulse Compression for Portable Drone-Disabling UWB Sources
A bipolar VIG and peaking gap compress voltage pulses into portable UWB emissions that disable drones with fast setup and low collateral effects.
- Vertical Photomixer Nanowire Electrode Heat Dissipation
A vertical photomixer uses a nanowire grid top electrode to reduce device capacitance and increase photocurrent.
- Segmentally Time-Variant Antenna for VLF Transmission
Modulating plasma segment conductivity prevents pulse reflection, resolving the contradiction between small antenna size and radiation efficiency.
- Antenna Configuration for Microwave Pulses Using Semiconductor Switching
Replacing mechanical spark gaps with avalanche breakdown diodes in a flat electrode antenna improves emission time reproducibility and extends service life.
- TEM Array Antenna Modular Fabrication
Modular unit cells simplify fabrication of TEM array antennas, achieving dual polarization and wide bandwidth while overcoming mechanical tolerance issues.
