This paper presents a novel tangential electric-field sensor with an embedded integrated balun for sensing up a tangential electric field over a circuit surface in the near-field measurements covering the GPS band. The integrated balun is embedded into the sensor to transform the differential voltage induced by the electric dipole into the single output voltage. The measurement system with a high mechanical resolution for the characterizations and tests of the sensor is detailed in this paper. The frequency response of the sensor characterized by a microstrip line from 1.35 GHz to 1.85 GHz (covering the GPS band) is rather flat. The rejection to the magnetic field of the sensor is up to 20.1 dB. The applications and validations of the sensor are conducted through passive/active circuit measurements.

AbstractA generalized technique has been developed that reduces the contributions of nonlinear effects that occur during measurements of natural electric fields around thunderstorms by an array of field mills on an aircraft. The nonlinear effects can be due to nearby charge emitted by the aircraft as it acquires and sheds charge, but the nonlinear effects are not limited to such sources. The generalized technique uses the multiple independent measurements of the external electric field obtained during flight to determine and remove nonlinear contaminations in the external vector electric field. To demonstrate the technique, a simulated case with nonlinear contaminations was created and then corrected for the nonlinear components. In addition, data from two different field programs utilizing two different aircraft and field mill configurations, each containing observable and different nonlinear effects, were also corrected for the significant nonlinear effects found in the field mill outputs. The expanded independent measurements in this new technique allow for the determination and correction of components in the field mill outputs from almost any measurable source. Alternate utilization of the technique can include removing effects in the aircraft charging such as aircraft altitude, cloud properties, engine power settings, or aircraft flap deployment. This technique provides a way to make more precise measurements of the true external electric field for scientific studies of cloud electrification.

The traceability of underwater electric field sensors is to track the most essential reason for underwater electric field generated by the sensor.When exploring marine electromagnetic field by underwater electric field sensors ,the underwater electric field sensor calibration traceability of the underwater electric field directly affects the final research significance .Therefore,the underwater electric field sensor calibration traceability technique is very important.The underwater electric field sensor calibration traceability is still in its infancy in our country recently .In this paper,underwater electric field sensor calibration traceability based on Ohm's law and magnetic field gradient methods are proposed through theoretical analysis and numerical simulation,which provide test methods for our underwater electric field sensor calibration and solve the bottleneck problem of underwater electric field measurements.

In this paper, we present a new design of the interferometer, intended for high-precision measurements of electric fields. We combined both arms of the interferometer in one segment of the fiber and the electric field sensor. The interferometer made using this scheme has a high resistance to mechanical and thermal fluctuations.
