High-Power, Compact, Ultra-Wideband PulserIn developing a pulsed ultra-wideband (UWB) radiation system some of the primary requirements are short pulse-width, jitter-free operation, and portability. The optical system which we present addresses all of these issues.作者: Maximize 時(shí)間: 2025-3-22 07:24
Measurements of Dielectric Properties of LiquidsA method for measuring the dielectric properties of liquids has been developed. The measurements (transmission or reflection) are performed in time domain using a special TEM sample holder. From the measured data the complex permittivity is calculated. The results show good agreement with data obtained using frequency domain experiments.作者: tympanometry 時(shí)間: 2025-3-22 12:14

Generation of THz Radiation from Semiconductorsd electromagnetic pulses were developed.. In particular, the development of chirped laser amplifiers allowed the generation of femtosecond electromagnetic pulses with peak power greater than one megawatt.. These pulses will have a significant impact on far-infrared spectroscopy and materials characterization.作者: JUST 時(shí)間: 2025-3-22 23:27

The Use of Optically Triggered, High Gain GaAs Switches for UWB Pulse Generationo the load is, at least, 44 MW. The small trigger energy and switch jitter are due to a high gain switching mechanism in GaAs. This experiment also shows a relationship between the rise time of the voltage across the switch and the required trigger energy and switch jitter.作者: Conclave 時(shí)間: 2025-3-24 07:51 作者: 我要沮喪 時(shí)間: 2025-3-24 11:26
