Paper Abstract

An infrared (IR) measurement technique has been developed to measure electromagnetic (EM) fields. This technique produces a two-dimensional IR thermogram of the electric or magnetic field being measured, i.e., an isothermal contour map of the intensity of the EM field. The intensity levels (equi-color levels) of the IR thermograms are empirically calibrated using standard gain horn antennas at several frequencies, angles of incidence, and polarizations in the near and far fields of the antenna. The results of the initial calibration test for electric field measurements are presented for a lossy Kapton detector screen developed to measure the absolute magnitude of the electric field in the plane of the detector screen. The accuracy of the technique is also discussed.
