Design, construction, and calibration of pseudo-transparent, non-interfering electric and magnetic field sensors

For nonuniform, nonplanar electromagnetic fields, knowledge of the magnitude and phase of each of the three orthogonal components of both the electric field and the magnetic field is required to completely characterize the field. Electrically small, polarization selective, electric and magnetic field sensors for measurement in the UHF band have been designed, constructed, and calibrated. These sensors are short dipoles (for electric fields) and small loops (for magnetic fields) with RF diodes across their gaps. The rectified RF is transferred down semiconductor (carbon-filled) lines to a DC voltmeter. Calibration of the sensors was accomplished in a TEM cell transmission line
