If the electrode is embedded in an insulator, isn't the sensing process dielectric polarization rather than electrostatic induction?

The following text is quoted from 「Application Note "Qvar sensing" (AN5755) p2.

「 A signal is derived from the electronic circuit due to the fluctuations in the electric field resulting from the passage of the charged particles. If the electrode is embedded in an insulator or there is no direct contact between the electrode and the particles, the sensing process is achieved through electrostatic induction. 」

Hi @Shion ,

When the electrode is embedded in an insulator, the sensing process at the electrode is primarily electrostatic induction, but it is strongly influenced by dielectric polarization of the surrounding insulator.
