Abstract

Continuous spectrum radiation in the frequency range of 2–4 GHz is generated by a plasma relativistic source. The pulsed radiation is fed into a rectangular waveguide measuring 72 × 34 mm² with the substance under study. A piston is inserted into the waveguide, and the refractive index of the substance is determined by the appearance of the interference pattern. The substance in the waveguide can be a gas or have the form of a rectangular bar or a cuvette with liquid. It can be used for spectroscopy of dielectrics.

应用噪声辐射测定2-4 GHz范围内气相和凝聚态物质的折射率

等离子体相对论源产生2 ~ 4ghz频率范围内的连续频谱辐射。脉冲辐射被送入一个尺寸为72 × 34 mm2的矩形波导中，其中含有所研究的物质。在波导中插入一个活塞，物质的折射率由干涉图样的外观决定。波导中的物质可以是气体，也可以是矩形棒或液体小管的形式。它可用于电介质的光谱学。
