Abstract

The finite-difference time-domain method is applied to the analysis of radiation from shielding enclosures with internal sources. Results from the three-dimensional code which has been developed are compared with analytical results from waveguide problems and the Lawrence Livermore TSAR code. Two enclosure examples are given to demonstrate the utility of the FDTD method for this application. One example is for radiation from slots, and the other is coupling of energy from a nonresonant aperture to an attached shielded cable that results in enhanced radiation
