DC electric field measurement in the SEEK Campaign

Campaign Rhetoric and the Hide-&-Seek Game

We present a model of political campaigning where a candidate chooses between promoting oneself (positive campaign) or attacking the rival (negative campaign). The media validates the claims made by candidates, and the quality of a candidate is not revealed unless there is a debate about her suitability, i.e. she is the subject of both a positive and a negative campaign. Negative campaigns may ...

Radar observations of field-aligned plasma irregularities in the SEEK-2 campaign

During the Sporadic E Experiment over Kyushu 2 (SEEK-2) campaign, field-aligned irregularities (FAIs) associated with midlatitude sporadic-E (Es) layers were observed with two backscatter radars, the Lower Thermosphere Profiler Radar (LTPR) and the Frequency Agile Radar (FAR), which were located 40 km apart in Tanegashima, Japan. We conducted observations of FAI echoes from 31 July to 24 August...

ELF Electric and Magnetic Field Measurement Methods

This paper surveys the instrumentation, calibration procedures, measurement techniques, and standards which can be used to characterize extremely low frequency (ELF) electric and magnetic fields. While the focus of the paper is on power frequency and power frequency harmonic fields, the measurement methods discussed are appropriate in principle for other ELF frequencies.
