Orthogonal Magnetic Loop Antenna for Lightning Detection
نویسندگان
چکیده
Lightning discharge emits RF energy over a wide range of frequencies. During cloud to ground lightning, when high currents occur in previously ionized channels, the most powerful emissions occur in the Very Low Frequency range. VLF (very low frequency) refers to radio frequencies spectrum range of 3 kHz to 30 kHz. Detection of lightning makes it possible to avoid various harmful effects occurring due to the discharge. In this paper, we have discussed various methods used to detect lightning in LF/VLF (low frequency/very low frequency) range. Cross magnetic Loop antenna designed and used here to receive lightning in the range of 3 – 30 kHz based on TOA (Time of Arrival) method.

متن کاملElectromagnetic Field Due to Lightning Strikes to Mountainous Ground
The produced electric and magnetic fields due to lightning strikes to mountainous ground are determined in this paper. For the sake of simplicity a cone-shaped ground with finite conductivity is assumed to represent a natural nonflat ground. By this assumption, we deal with an axillary symmetrical structure so we use the cylindrical 2D-FDTD to save the simulation memory and time, dramatically. ...
