A new type electrooptical electromagnetic field probe was fabricated by combining three magnetic field sensors, each of which consists of a Mach-Zehnder modulator and an integrated annular antenna. The frequency response was flat from 50 MHz to 2.2 GHz. The average minimum detectable electromagnetic field intensity of the sensor is 2.22 mV/m. When the probe axis was pointed toward the electromagnetic...
Some results of measuring low-frequency magnetic fields of various objects (orbital stations, cars, rails) with the help of mobile information-measuring system "Kaskad" are presented in the report. The aims of such measurements are: for the first and the second kinds of objects - comparison of measured values with permissible levels of national standards, for the third technical diagnostics...
