摘要

利用空腔摄动技术研究了食用蚱蜢(Sphenarium purpurascens)在2.4 GHz的介电特性。样品经受温度升高(从25°C到80°C)。结果表明,随着温度的升高,介电常数的实部有减小的趋势。随着温度升高,水蒸发;因此介电常数值减小。此外,介质损耗随着温度的升高而增加,从25℃时的16增加到80℃时的32。这是由在较低频率下的主要离子传导引起的,其中离子迁移率在较高温度下增加。穿透深度从25℃时的10.8 mm减小到80℃时的3.5 mm。

Dielectric properties of Sphenarium purpurascens at 2.4 GHz
Abstract The dielectric properties of edible grasshoppers (Sphenarium purpurascens) are presented at 2.4 GHz using the cavity perturbation technique. The samples are subjected to increasing temperatures (from 25 to 80 °C). It will be shown that the real part of the permittivity has a decreasing trend to rising temperature. As temperature increases, water evaporates; therefore the value of permittivity decreases. Moreover, dielectric losses increase with increasing temperature from 16 at 25 °C to 32 at 80 °C. This is caused by a predominant ionic conduction at lower frequencies, where ionic mobility increases at higher temperatures. In addition, the penetration depth decreases from 10.8 mm at 25 °C to 3.5 mm at 80 °C.
