Generation of standard EM fields for calibration of power density meters 20 kHz to 1000 MHz
Abstract
The report describes techniques for calibrating power density meters used by the Department of Defense in measuring high intensity (hazard level) RF fields in the frequency range 20 kHz to 1000 MHz. Several techniques were considered for producting a standard field including parallel plate and parallel wire transmission lines, transverse electromagnetic mode (TEM) transmission cells, various directive antennas, and open ended waveguide (OEG). The major emphasis is on the TEM cells, which are recommended for the frequency range 20 kHz to 500 MHz. Design and evaluation details and an error analysis are discussed.
