Abstract
In this study, mainly, in order to propose some evaluation methods to the research for correlative and/or accumulative effect in waved environmental problem, a fairly complicated fluctuation form of the especially complicated near-by electromagnetic (abbr. EM) field leaked from an information terminal equipment (abbr. ITE) group under the parallel operation has been noticed. Concretely, differing from the early EM theory by Middleton started from its physical mechanism, for these compound fluctuation forms, a probability distribution expression of statistical Hermite orthonormal series expansion type on the basis of the well-known Gaussian distribution and a probability distribution expression of statistical Jacobi orthonormal series expansion type on the basis of the beta distribution which can flexibly deal with even complex features such as the asymmetry and/or the bimodality have firstly introduced, and the technique which can flexibly evaluate the electric and/or magnetic field strength distributions under such a complicated situation has been proposed. Finally, with an application to measured data in the ITE group in the actual working environment, a part of the effectiveness of this method has been also experimentally confirmed.
