 note = {application, An electric field sensor with a parametric oscillation is described. It is composed by a time variable inductor and ceramic condenser. A time variable inductor is realized by a 3L-R mutator, and is used for the adjustment of the parametric oscillation frequency. In this paper, it is found that the configuration of the electric field sensor is shown in detail. Also, the oscillation voltage in the frequency range of 1kHz is obtained.},
