    • A system and method for probing a specimen to determine one or more components by utilizing a first signal to excite the specimen at a nuclear quadrupole resonant frequency and observing changes in a specimen property. One exemplary property may be dielectric constant. Another exemplary property may be magnetic permeability. In one embodiment, the first signal is unmodulated and a second signal is observed for the presence of modulation at the frequency of the first signal. Alternatively, the first signal may be modulated and the second signal may be observed for the presence of the modulation. A system is disclosed wherein the specimen is excited using the first frequency and a radar at the second frequency is used to observe changes in radar reflectivity of the specimen due to the excitation.
    • 一种用于探测样本以通过利用第一信号以核四极共振频率激发样本并观察样品特性变化来确定一个或多个组分的系统和方法。 一个示例性的性质可以是介电常数。 另一个示例性的性质可以是磁导率。 在一个实施例中,第一信号是未调制的,并且在第一信号的频率处观察到存在调制的第二信号。 或者,可以调制第一信号,并且可以观察到第二信号的调制存在。 公开了一种系统,其中使用第一频率激励样本,并且使用第二频率的雷达来观察由于激发而导致的样本雷达反射率的变化。
