Resumen
We start with the fact that the actual consensus on the empirical verification of the standard
retardation condition does not take into account the complex structure of the whole electromagnetic
field in the near zone. The most rigorous and methodologically consistent way to the empirical test
of the causal behavior of the whole EM field should be based on testing causal properties for each
component—velocity dependent bound and acceleration dependent radiation —taken separately.
Preliminary discussions on the relative contribution of bound and radiation terms for an idealized
magnetic dipole provided us with a methodological approach to causal characteristics of bound
fields. In view of practical implementation of this method, we made an analysis of the finite size
loop antennas. The use of multisection loop antennas was fully justified by a substantial rise of the
ratio of bound-to-radiation field strength. Finally, we effected numerical calculations, taking into
account particular experimental settings. Comparison with the experimentally obtained data showed
considerable discrepancy with the predictions of the standard electromagnetic theory. A possible
interpretation in terms of nonlocal properties of bound fields in near zone is proposed. Producción Científica de la Universidad Autónoma de Zacatecas UAZ
