High Power Electromagnetic Transient Pulse in-Phase Synthesis

Abstract

PCSS low jitter trigger can reach 65 ps in the condition of high bias electric under the non-liner mode [1-5]; high power transient pulse can be gained by virtue of it. The high power transient pulse in-phase characteristic and other tenets are verified by testing axial electric field strength and axial energy density, which is energy per area at the antenna main radiation direction. In the experiment, axial electric field strength and energy density of antenna array measured in different conditions indicate that axial electric field strength is proportional to the number of antenna elements and the energy density is proportional to the square of the number of radiation units, which means the transient electromagnetic pulses could synthesize in phase perfectly.

Evaluation of Mechanical Properties and HPM Pulse Shielding Effectiveness of Cement-Based Composites

“…Another material that is promising with regard to microwave radiation absorption effectiveness is nickel [30]. It was shown in [31] that, owing to this material's high magnetic transformation temperature, a stable electromagnetic wave absorption capacity is achieved. Additionally, worth noting are iron powders, which were shown to be suitable for absorbing composites by the authors of [32].…”

Arbitrary Waveform Generator Based on GaAs FET and Tapered Micro-Strip Line

“…It can generate ultra-wide band low voltage pulse with high stability. Because the laser driver shape in inertia confinement fusion (ICF) experiment particularly works with narrow width and wide dynamic range, it is a key technology to generate this kind of electrical pulse [3,4]. The electrical pulse is usually used to drive the optical waveguide modulator to obtain shaped laser pulse.…”
