“…The optical receiver transforms the received signals into voltages, which can be displayed in the sampling oscilloscope with a maximal resolution of 20 GS/s. The measurement with the GTEM 1250 differs mainly in the used field sensors: Here, the measurement setup consists of two passive probes developed in [5] or [6]. The electric field components are measured with a bipolar conical electrical dipole and the magnetic field components are measured with a loop antenna.…”

This paper concentrates on the usage of the IEC 61000-4-20, the international standard for emission and immunity testing in transverse electromagnetic (TEM) waveguides. The specifications for transient testing in TEM waveguides according to Annex C of the norm are verified by measurements with different waveguides (GTEM 1250 and GTEM 3750) and various excitation signals with a large bandwidth up to several GHz. The measurement results show that the norm can be enlarged related to the defined limits of the applied test signals and the usable testing volume in the waveguide.

Recent in-flight, direct-strike lightning research, using a NASA F-106B aircraft, is reviewed. An instrumentation system which records the rates of change of electric and magnetic flux density at several locations on the aircraft and rate of change of strike current to the boom is described. The measurement parameters are the rate of change of electric flux density over a range of 50 A/m 2 , rate of change of magnetic flux density over a range of 20,000 T/s, and rate of change of strike current over a range of 100 kA/>s. The isolated and shielded instrumentation system employs high-sample-rate digital transient recorders with augmented memory capacity and a wide-band analog recorder for data acquisition and recording. The data obtained during the 1980 flight test program are presented, and the data significance is discussed.

“…Many electric-field sensing applications require sensors capable of measuring fields in difficult to reach environments with minimal field perturbation [1][2][3]. Slab-coupled optical sensors (SCOSs) provide an effective alternative for electric-field sensing applications requiring small, minimally intrusive electricfield sensors.…”

Improvements in electric-field sensor sensitivity by exploiting a tangential field condition

et al. 2013

View full text Add to dashboard Cite

This paper presents improvements to slab-coupled optical fiber sensors for electric-field sensing. The sensors are comprised of a potassium titanyl phosphate (KTP) crystal mounted on a D-fiber. The improvements are based on changing the crystal orientation, which enhances sensitivity due to a combined increase in the effective electro-optic coefficient and electric-field penetration into the KTP crystal. The paper provides a detailed comparison of the improved sensor, which uses x-cut KTP to the previous sensor design using z-cut KTP. The measurements show an 8.6× improvement in the sensitivity.
